Jeff Hardy is the son of Gilbert and Ruby Moore Hardy, and the younger brother of Matt Hardy. Their mother died of brain cancer in 1986, when Jeff Hardy was nine. He developed an interest in motocross aged 12 and got his first bike, a Yamaha YZ-80, at age 13. He had his first race when he was in ninth grade. Hardy played baseball when he was young, but had to stop after he crashed during a motocross race, injuring his arm. He also played football during high school as a fullback and linebacker. He briefly competed in amateur wrestling in high school. He had to stop playing football in high school, after he was ordered to pick between professional wrestling and football, and he chose wrestling. Hardy’s favorite subjects in school were U.S. history and art, which he did for extra credit.

Hardy cites Hulk Hogan, The Ultimate Warrior, and Shawn Michaels as his childhood inspirations to wrestle. He started on World Wrestling Federation (WWF) television as a jobber—a wrestler who consistently loses to make his opponents look stronger. His first WWF match was against Razor Ramon on May 23, 1994 in Youngstown, Ohio, with Randy Savage mentioning on commentary, “Welcome to the big time”. His ringname that night, Keith Davis, was the name of Razor’s scheduled jobber, who backed out on short notice. Gary Sabaugh, who had brought Hardy in a group along with Davis, suggested him to agent Tony Garea, who agreed after Hardy claimed he was 18 (he was in fact, only 16). The next day, he wrestled under his real name against The 1–2–3 Kid, and the match aired on the June 25 episode of Superstars. He occasionally wrestled as a jobber as late as 1997 (including a match against Rob Van Dam during the ECW “invasion” storyline that had Hardy billed as being from Virginia instead of Cameron, North Carolina) before beginning his first major run in 1998.

Before arriving in the WWF, Jeff and Matt formed their own wrestling promotion, the Organization of Modern Extreme Grappling Arts (OMEGA) with Thomas Simpson. The promotion was a more successful version of the original TWF and included talent such as both Hardy brothers, Shannon Moore, Gregory Helms, Joey Matthews, and Steve Corino, among others. In OMEGA, each of the brothers portrayed several different characters; Hardy portrayed such characters as Willow the Wisp, Iceman, Mean Jimmy Jack Tomkins, and The Masked Mountain. While there, Hardy held the New Frontier Championship (NFC) as a singles competitor and the Tag Team Championship with Matt. The promotion folded in April 1998 when they signed contracts with the WWF.

The Hardy brothers eventually caught the eyes of the World Wrestling Federation (WWF). After being signed to a contract in 1998, they were trained by Dory Funk Jr. in his Funkin’ Dojo with other notable wrestlers such as Kurt Angle, Christian, Test, and A-Train. When the team was finally brought up to WWF television, after months of “jobbing” and live events, they then formed the acrobatic tag team called the Hardy Boyz. While feuding with The Brood in mid-1999, they added Michael Hayes as their manager. On July 5, they won their first WWF Tag Team Championship by defeating the Acolytes, but lost it back to them a month later. After the dissolution of the Brood, the Hardys joined forces with Gangrel as The New Brood and feuded with Edge and Christian. This stable did not last long, however, and on October 17, 1999 at No Mercy, the Hardy Boyz won the managerial services of Terri Runnels in the finals of the Terri Invitational Tournament in the WWF’s first ever tag team ladder match against Edge and Christian. They competed in the first ever tag team triple threat ladder match against The Dudley Boyz, and Edge & Christian at WrestleMania 2000, in which Edge & Christian won. During the match, Hardy performed a Swanton Bomb to Bubba Ray Dudley off a 20-foot ladder.

Hardy has a tattoo of roots that starts on his head, behind his ear, and finishes at his hand. He also has a few other signature designed tattoos, one of which, a dragon, he hid from his father at a young age. It was also the first tattoo he got in 1998. He later got tattoos of the Chinese symbols for “Peace” and “Health”, as well as tattoos of fire and a wave. On March 13, 2020, after a match with King Corbin, Hardy revealed a new tattoo on his back. Hardy regards his tattoos as his “artistic impulses”. Hardy is very good friends with Shannon Moore, whom he has known since around 1987. He is also good friends with Marty Garner, Jason Arhndt, and John Morrison as well as Gregory Helms, having known him since the early 1990s. He and Matt also helped train Shane. He regards Vanilla Ice as a big influence on him, and he was even nicknamed “Ice” by Scott Hall.

Hardy met his girlfriend Beth Britt in 1999, shortly after the Hardy Boyz had won the WWF Tag Team Championship for the first time. Hardy and his brother Matt went to a club in Southern Pines, North Carolina, where Hardy met her. On March 15, 2008, it was reported that Hardy’s house had burned to the ground in a fire. Hardy and his girlfriend Beth were not home at the time, but his dog, Jack was killed in the fire. In October 2008, Hardy was building a new home in the same area before, which was expected to be completed by early January 2009. In August 2010, Hardy announced that Britt was pregnant with the couple’s first child, a daughter named Ruby Claire Hardy, who was born on October 19, 2010. The pair’s second child, a daughter, Nera Quinn Hardy, was born on December 31, 2015. Hardy married Britt on March 9, 2011.

In 2000, the Hardy Boyz found a new manager in their real-life friend Lita. Together, the three became known as “Team Xtreme”. They continued their feud with Edge and Christian throughout 2000, defeating them for the WWF Tag Team Championship on two occasions. At SummerSlam, the Hardy Boyz competed in perhaps the most physically demanding type of match they had competed in thus far- the first ever Tables, Ladders, and Chairs match (TLC match)- in their hometown of Raleigh, for the Tag Team Championship against the Dudley Boyz and Edge & Christian, but were unsuccessful. The second TLC match at Wrestlemania 17 in Houston, which is regarded as one of the greatest matches in WWE history they faced off once again against Edge & Christian and the Dudley Boyz but lost to the former.

Hardy gained attention for his high risk stunts in the TLC matches, such as doing Swanton Bomb frontflips off of the top steps of 10 and 20 foot high ladders, making a name for himself as one of the most seemingly reckless and unorthodox WWF performers of his time. In 2001, Hardy received a push as a singles competitor, and he held the Intercontinental (defeating Triple H), Light Heavyweight (defeating Jerry Lynn) and Hardcore Championships (defeating Mike Awesome and Van Dam on two separate occasions). At the end of 2001, the Hardys began a storyline in which they began to fight, which led to Matt demanding a match at Vengeance, with Lita as the special guest referee. After Hardy beat Matt by pinfall at Vengeance, while Matt’s foot was on the ropes, Hardy and Lita began feuding against Matt. In the middle of the feud, however, Hardy faced The Undertaker in a Hardcore Championship match and lost. After the match, The Undertaker was scripted to attack both Hardy and Lita, injuring them. On the next episode of SmackDown!, The Undertaker attacked Matt as well, also injuring him, in storyline. The Hardys and Lita were not seen again until the Royal Rumble, because WWF did not have another storyline for their characters. The Hardys later came back as a team, and there was never any mention of their previous storyline split.

Hardy appeared on the February 7, 1999 episode of That ’70s Show entitled “That Wrestling Show”, along with Matt, as an uncredited wrestler. Hardy and Matt also appeared on Tough Enough in early 2001, talking to and wrestling the contestants. He appeared on the February 25, 2002 episode of Fear Factor competing against five other World Wrestling Federation wrestlers. He was eliminated in the first round. His brother eventually won the $50,000 for his charity. Hardy also appears on The Hardy Show, an internet web show which features the Hardys, Shannon Moore and many of their friends. In September 2009, Hardy signed a deal with Fox 21 to appear in a reality television show.

In 2001, Hardy, Matt and Lita appeared in Rolling Stone magazine’s 2001 Sports Hall of Fame issue. In 2003, Hardy and Matt, with the help of Michael Krugman, wrote and published their autobiography The Hardy Boyz: Exist 2 Inspire.

In early April 2002, the Hardy Boyz began a feud with Brock Lesnar after Lesnar gave Matt an F-5 on the steel entrance ramp, which led to an angered Hardy seeking revenge on Lesnar. At Backlash, Hardy faced-off against Lesnar in Lesnar’s first televised match. Lesnar dominated Hardy and won the match by knockout. Lesnar and the Hardys continued to feud over the next few weeks, with the Hardys coming out victorious only once by disqualification. At Judgment Day, Lesnar gained the upper hand on the Hardy Boyz before tagging his partner, Paul Heyman, in to claim the win for the team. In July 2002, Hardy won his third Hardcore Championship by defeating Bradshaw.

In late 2002, Hardy had been teaming with Rob Van Dam and Bubba Ray Dudley. He along with Bubba Ray and Spike Dudley defeated 3-Minute Warning at Survivor Series in a six-man tag team elimination tables match.

In January 2003, Hardy briefly turned into a heel (villain) after he attacked Van Dam and Shawn Michaels. It ended a month later when he saved Stacy Keibler from an attack by then-villain, Christian. In February, he had a brief program with Michaels, which saw the two team up. Then, in storyline, Hardy began dating Trish Stratus after saving her from Steven Richards and Victoria in March. Hardy and Stratus had a brief on-screen relationship that saw the duo talking backstage and teaming together in matches. Hardy competed in his final match (his first departure) against The Rock and lost. Hardy was released from WWE on April 22, 2003. The reasons given for the release were Hardy’s erratic behavior, drug use, refusal to go to rehab, deteriorating ring performance, as well as constant tardiness and no-showing events. Hardy also cites “burn out” and the need for time off as reasons for leaving WWE.

Hardy taught himself how to play guitar and later purchased a drum set. In 2003, Hardy formed a band, PeroxWhy?Gen, with members of the band Burnside 6 and Moore, who later left. He also converted a trailer into a recording studio. Their first album (marketed as a Jeff Hardy solo album) Plurality of Worlds was released through TNA Music on November 7, 2013. Peroxwhy?Gen released their second album Within the Cygnus Rift on July 27, 2015.

Hardy debuted in Total Nonstop Action Wrestling (TNA) on June 23, 2004, at the Second Anniversary Show, in a match against A.J. Styles, for the TNA X Division Championship. He also debuted his new entrance theme “Modest”, a song performed by Hardy himself, and a new nickname, “The Charismatic Enigma”. The match ended in a no contest when Kid Kash and Dallas interfered. Hardy returned to TNA on July 21 and was awarded a shot at the NWA World Heavyweight Championship. Hardy challenged for the title on September 8, losing to NWA World Heavyweight Champion Jeff Jarrett. In October 2004, he won a tournament, earning a shot at the NWA World Heavyweight Championship on November 7 at Victory Road, TNA’s first monthly pay-per-view. Hardy was defeated by Jarrett once again in a ladder match at Victory Road following interference from Kevin Nash and Scott Hall.

One month later at Turning Point, Hardy, Styles and Randy Savage defeated Jarrett, Hall and Nash (collectively known as the Kings of Wrestling). Hardy went on to defeat Hall in a singles match, substituting for Héctor Garza at Final Resolution on January 16, 2005.

At Against All Odds in February 2005, Hardy lost to Abyss in a “Full Metal Mayhem” match for the number one contendership to the NWA World Heavyweight Championship. Hardy returned the favor by defeating Abyss in a Falls Count Anywhere match at Destination X in March. On March 25, 2005, Hardy teamed with Shocker defeating David Young and Lex Lovett. Hardy then went on to feud with Raven, Hardy defeated Raven in a Six sides of steel match at Lockdown in April. Hardy was suspended from TNA after no-showing his “Clockwork Orange House of Fun” rematch with Raven at Hard Justice on May 15, allegedly due to travel difficulties. Hardy’s suspension was lifted on August 5, and he returned at Sacrifice approximately a week later, attacking Jeff Jarrett.

Hardy was scheduled to wrestle on the pre-show of Turning Point in December 2005, but once again no-showed the event, again citing traveling problems. Hardy was suspended as a result and did not appear on TNA television again. In March, April, and May 2006, Hardy appeared on several live events promoted by TNA in conjunction with Dave Hebner and the United Wrestling Federation. Hardy was later released from his TNA contract in June 2006.

On August 4, 2006, WWE announced that Hardy had re-signed with the company. In the following weeks, vignettes aired hyping his return on the August 21 episode of Raw. On the day of his return, Hardy confronted then WWE Champion Edge, before an altercation between the two that ended when Lita pulled Edge out of the ring, preventing Hardy from delivering a Swanton Bomb. After failing to capture the Intercontinental Championship from Johnny Nitro over the next few weeks, including at Unforgiven, Hardy finally defeated Nitro to win his second Intercontinental Championship on the October 2 episode of Raw. On the November 6 episode of Raw, Hardy lost the Intercontinental Championship back to Nitro, after Nitro hit him with the Intercontinental Championship title belt. One week later, Hardy regained it on the November 13 episode of Raw, with a crucifix pin. This marked Hardy’s third reign as Intercontinental Champion.

With Hardy still feuding with Johnny Nitro and the other members of MNM into 2007, he was challenged once again by Nitro at New Year’s Revolution in a steel cage match for the Intercontinental Championship. Hardy once again defeated Nitro. Hardy then teamed with Matt to defeat MNM at both the Royal Rumble and No Way Out pay-per-views. The next night on the February 19 episode of Raw, Hardy lost the Intercontinental Championship to Umaga. In April 2007, Hardy competed in the Money in the Bank ladder match at WrestleMania 23. During the match, Matt threw Edge onto a ladder and encouraged Hardy, who was close to the winning briefcase, to finish Edge off. Hardy then leaped off the 20-foot-high (6.1 m) ladder, drove Edge through the ladder with a leg drop, injuring both Edge and himself. The two were unable to continue the match and were removed from ringside on stretchers.

On June 23, 2008, Hardy was drafted to the SmackDown brand as a part of the 2008 WWE draft. Hardy made his debut for the brand on the July 4 episode of SmackDown, defeating John Morrison. Hardy participated in the WWE Championship Scramble match at Unforgiven and also challenged for the championship at No Mercy and Cyber Sunday, but failed to win each time. He was originally scheduled to be in the WWE Championship match at Survivor Series, but, in storyline, was found unconscious in his hotel stairwell, allowing the returning Edge to replace him in the match and win the title. At Armageddon, Hardy defeated Edge and Triple H in a triple threat match to capture the WWE Championship, his first world championship.

As part of WWE, Hardy has appeared in several of their DVDs, including The Hardy Boyz: Leap of Faith (2001) and The Ladder Match (2007). He is also featured in the Total Nonstop Action Wrestling release Enigma: The Best of Jeff Hardy (2005) and Pro Wrestling’s Ultimate Insiders: Hardy Boys – From the Backyard to the Big Time (2005). On April 29, 2008, WWE released “Twist of Fate: The Matt and Jeff Hardy Story”. The DVD features footage of the brothers in OMEGA and WWE, and also briefly mentions Hardy’s first run with TNA. In December 2009, WWE released a DVD about Hardy entitled Jeff Hardy: My Life, My Rules. In 2012 Total Nonstop Action released “Enigma: The Best Of Jeff Hardy Volume 2”, a followup to the 2005 release featuring a 2 disc long documentary following Hardy’s return to TNA, his heel turn, and the Victory Road 2011 incident, and is accompanied by the matches spoken about. In 2015, Total Nonstop Action release “The Best of Jeff Hardy Volume 3: Humanomoly”, featuring some of his greatest matches throughout his TNA tenure.

In January 2009, Hardy’s next storyline led to his involvement in scripted accidents, including a hit-and-run automobile accident and an accident involving his ring entrance pyrotechnics. At the Royal Rumble, Hardy lost the WWE Championship to Edge after Hardy’s brother, Matt, interfered and turned on Hardy, hitting him with a steel chair. The buildup to this feud involved Matt implying that he was responsible for all of Hardy’s accidents over the past few months, and at WrestleMania 25, Matt defeated Hardy in an Extreme Rules match and in a stretcher match on the April 10 episode of SmackDown. In a rematch at Backlash, however, Hardy defeated Matt in an “I Quit” match to end the feud.

On September 11, 2009, Hardy was arrested on charges of trafficking in controlled prescription pills and possession of anabolic steroids, after a search of his house yielded 262 Vicodin prescription pills, 180 Soma prescription pills, 555 milliliters of anabolic steroids, a residual amount of powder cocaine, and drug paraphernalia. Over a year later, the district attorney announced that Hardy would plead guilty to the charges. On September 8, 2011, Hardy was sentenced to ten days in jail, 30 months of probation, and a fine of $100,000. Hardy served his jail sentence from October 3 to 13, 2011.

On TNA’s first live Monday episode of Impact! on January 4, 2010, Hardy made his return to TNA, along with Shannon Moore. He was attacked by Homicide after emerging from the crowd, but hit Homicide with a steel chair and performed the Twist of Fate on the Impact! Zone ramp. He later appeared in backstage segments throughout the evening. The following day, it was reported that Hardy had signed a new contract with TNA. Hardy would make his next appearance for the company on the March 8 episode of Impact!, saving D’Angelo Dinero, Abyss and Hulk Hogan from A.J. Styles, Ric Flair and Desmond Wolfe. The following week, Hardy defeated then TNA World Heavyweight Champion A.J. Styles in a non-title match.

Hardy’s professional wrestling style has been described as “high-flying” and “death-defying” with “daredevil stunts”. His signature finishing move is the Swanton Bomb. However, by 2018, Hardy used the Swanton Bomb less frequently due to his accumulated lower back injuries. Hardy also uses the Twist of Fate, a ⁄4 Facelock cutter or a ⁄4 facelock stunner. During his time as a heel in 2010, the Twist of Fate was renamed the Twist of Hate. Hardy’s other signature moves include Whisper in the Wind (a rolling senton bomb); Poetry in Motion; a sitout jawbreaker; and a double leg drop to the midsection of a supine opponent.

At Bound for Glory, Hardy turned heel with Hulk Hogan and Eric Bischoff and with their help defeated Angle and Anderson to win the TNA World Heavyweight Championship for the first time. They were then joined by Jeff Jarrett and Abyss, revealing the group that Abyss had been referring to as “they” for several months. On the following episode of Impact!, the stable was named Immortal, as it formed an alliance with Ric Flair’s Fortune. Meanwhile, Hardy debuted a new dark character, using cryptic messages as he explained the reasons behind his turn. At Turning Point, Hardy retained his title in a defense against Matt Morgan, a replacement for Mr. Anderson, who was sidelined after suffering a concussion during an attack by Hardy. On the following episode of Impact!, Hogan presented Hardy with a new design of the TNA World Heavyweight Championship, which he dubbed the TNA Immortal Championship.

On August 23, 2011, TNA announced that Hardy would be making his return to the promotion at the Impact Wrestling tapings on August 25 in Huntsville, Alabama. The return would take place only five days after Matt Hardy was released from his TNA contract.

Hardy wrestled his first match in six months on September 15 at a live event in York, Pennsylvania, defeating Jeff Jarrett.

Hardy made his in-ring return on the February 28 episode of Impact Wrestling, teaming with his new number one contender Bully Ray to defeat Bad Influence (Christopher Daniels and Kazarian).

At the Lockdown episode of Impact Wrestling, Hardy suffered a minor concussion which was set as a storyline injury when he fell on the door of the cage; James Storm hit Hardy off the door onto the steel steps below with a cowbell.

At Payback, The Hardy Boyz retained their championships against Cesaro and Sheamus, who attacked them after the match. The next night on Raw, Cesaro and Sheamus explained their actions, claiming the fans were more supportive of ‘novelty acts’ from the past like The Hardy Boyz, who they feel did not deserve to be in the match at WrestleMania 33. Subsequently, at Extreme Rules, The Hardy Boyz lost the titles against Cesaro and Sheamus in a steel cage match, and failed to regain it back the following month at the Great Balls of Fire event.

On the August 28 episode of Raw, Hardy won a battle royal by last eliminating Jason Jordan to become the number one contender for the Intercontinental Championship, but was unsuccessful in his challenge the following week.
