Jeon Jung-kook (Korean: 전정국) was born on September 1, 1997 in Busan, South Korea. His family consists of his parents and an elder brother. He attended Baekyang Elementary and Middle School in Busan. When he became a trainee, he transferred to Singu Middle School in Seoul. Jungkook initially had dreams of becoming a badminton player when he was young, but after seeing G-Dragon perform “Heartbreaker” on television, it influenced him to want to become a singer.

In 2011, Jungkook auditioned for the South Korean talent show Superstar K during its auditions in Daegu. Though he was not selected, he received casting offers from seven entertainment companies. He eventually chose to become a trainee under Big Hit Entertainment after seeing RM, now his fellow band member and leader in BTS, perform. To work on his dance skills in preparation for debut, he went to Los Angeles during the summer of 2012 to receive dance training from Movement Lifestyle. In June 2012, he appeared in Jo Kwon’s “I’m Da One” music video and also worked as a backup dancer for Glam before his debut. He graduated from Seoul’s School of Performing Arts, an arts high school, in 2017. In November 2016, he decided to forgo taking the CSATs, Korea’s nationwide university entrance exam, and is currently enrolled at Global Cyber University along with BTS members RM, J-Hope, Suga, V and Jimin. Jungkook has cited Justin Bieber, Justin Timberlake and Usher among his musical inspirations.

On June 12, 2013, Jungkook made his debut as a member of BTS with the release of the single 2 Cool 4 Skool. Under BTS, he has sung two solo tracks; the first, pop track “Begin” from the 2016 album Wings, told his story of moving to Seoul at a young age to become an idol and expresses his gratitude towards his fellow members for taking care of him during that time. The second track, a future bass song titled “Euphoria”, was released with an accompanying nine-minute short film on April 5, 2018 as the introduction to the third part of BTS’ “Love Yourself” series. The full studio track was included on their album Love Yourself: Answer on August 24, 2018. Euphoria was produced by DJ Swivel and charted at number five on the Billboard Bubbling Under Hot 100 Singles chart. It charted for 13 weeks on the World Digital Song Sales.

In September 2015, Jungkook participated in the “One Dream, One Korea” campaign, taking part in a song collaboration alongside numerous Korean artists in memory of the Korean War. The song was released September 24 and presented at the One K Concert in Seoul on October 15.

On November 6, 2018, Jungkook performed “We Don’t Talk Anymore” with original singer Charlie Puth in a special collaboration stage during the MBC Plus X Genie Music Awards. The song was one he had previously covered twice, solo and with fellow BTS member Jimin.

In a 2019 survey conducted by Gallup Korea, Jungkook ranked as the third most-loved celebrity of the year in South Korea. He debuted on the list in 2016 at 20th, then ranked 17th in 2017, and then 8th in 2018. In 2018, Jungkook placed first for 10 weeks in a row for magazine Hi China, under the most beloved celebrities list in China. Jungkook is also extremely popular on social media amongst fans. In October 2018, he broke the record of most real-time viewers with his solo live broadcast in V Live history, with more than 3.7 million viewers worldwide; in December 2018, a video of him singing in the studio became the most retweeted tweet in South Korea that year. Various artists have cited him as an influence and role model, such as Kim Dong-han and Hyeongseop X Euiwoong.

On June 4, 2020, Jungkook released the song “Still With You”, for free on platforms such as SoundCloud as a part of BTS’ yearly debut celebrations. Billboard described the song as having “tinkling synths and gently strummed guitars and brushed drums”. Jungkook produced the piece himself.
