Lauren Mayberry

Mayberry attended Beaconhurst School, an independent school in Bridge of Allan. After completing a four-year undergraduate law degree at the University of Strathclyde, she earned a master's degree in Journalism in 2010. This led her into a career in freelance journalism and production running. From 2009 to 2010 she was a contributor to the UK music website The Line of Best Fit.

In September 2011, Iain Cook of Aereogramme and The Unwinding Hours produced Blue Sky Archives' Triple A-Side EP. Cook started a new project with his friend Martin Doherty and asked Mayberry to sing on a couple of demos. They wrote together for seven or eight months in a basement studio in Glasgow. Cook, Mayberry and Doherty decided to form a new band after the sessions proved to be successful. The band chose the name Chvrches, using a Roman "v" to distinguish themselves from actual churches on internet searches.

In 2013, the band signed to Glassnote Records after releasing the tracks, "Lies" and "The Mother We Share" in 2012. Their debut EP, Recover, was released in 2013. The band released their debut album, The Bones of What You Believe, on 20 September 2013.

In September 2013, Mayberry wrote an article for The Guardian in response to misogynist messages she received online. She wrote:

She discussed the issue again in a Talks at Google session in 2014 and on Channel 4 News, following aggressive responses to the band's video for "Leave a Trace".

In 2015, Mayberry wrote about an abusive personal relationship for Jenni Konner and Lena Dunham's Lenny Letter. In December 2016, Mayberry took part in a fundraiser show with Carly Rae Jepsen, Lorde and Charli XCX for the Ally Coalition, an organisation started by Jack Antonoff to raise money for homeless LGBT youth.

Mayberry and actor Justin Long have engaged in multiple philanthropic activities together, including hosting a holiday variety show charity fundraiser at The Fonda Theatre in Los Angeles and travelling together to Nicaragua to visit a women's shelter. In May 2018, The Guardian identified Long as Mayberry's boyfriend. Mayberry has since suggested that these claims are false.

In September 2018, People reported that "[Justin] Long has split from Chvrches frontwoman Lauren Mayberry, whom he began dating in 2016." During an interview with Rolling Stone in October 2018, Mayberry indicated that she is single.
