Liam James Payne (29 August 1993 – 16 October 2024) was an English singer and songwriter. He was a member of the pop band One Direction, one of the best-selling boy bands of all time, alongside Niall Horan, Zayn Malik, Harry Styles, and Louis Tomlinson. Payne twice auditioned as a solo artist on the British television series The X Factor in 2008 and 2010; in the latter, he was invited to join One Direction alongside fellow contestants, placing third and later achieving global success.

Following One Direction's hiatus in 2016, Payne pursued a solo career, signing with Republic Records in North America. In 2017, he released his debut solo single "Strip That Down", which reached number three on the UK singles chart and number ten on the US Billboard Hot 100. The song received multi-platinum certifications in both countries. The following year, he released "For You", a collaboration with Rita Ora which became a hit worldwide and received gold or platinum certifications in several countries. His debut and sole solo album, LP1, was released in December 2019. During the first three years of his solo career, Payne sold over 18 million singles, 2.4 million albums, and amassed 3.9 billion streams. In addition to his solo work, Payne produced remixes under the pseudonyms Big Payno and Payno, remixing tracks for both his group and for singer Cheryl.

Payne struggled with substance abuse and mental illness throughout his career. On 16 October 2024, he died at the age of 31 after falling from a third-floor balcony at a hotel in Buenos Aires, Argentina, while intoxicated. Following his death, Payne's track "Teardrops" debuted on the UK singles chart, alongside the re-entry of 11 of his other works.

Liam James Payne was born at New Cross Hospital in the Heath Town district of Wolverhampton on 29 August 1993, the son of infant nurse Karen Payne and fitter Geoff Payne. He had two older sisters named Nicola and Ruth. Payne was born three weeks premature and suffered frequent illnesses. Until the age of four, he had regular tests done in hospital as doctors noticed one of his kidneys was scarred and dysfunctional. In the book Dare to Dream: Life as One Direction, he mentioned that before he was four, "I was always in hospital having tests done but they couldn't find out what was wrong. They discovered that one of my kidneys wasn't working properly and it had scarred. I had to have 32 injections in my arm in the morning and evening to try and make me better."

As a student, Payne was heavily involved in sports, particularly cross-country running. Payne joined the Wolverhampton & Bilston Athletics Club to pursue his running career.

He began taking boxing lessons at the age of 12 amidst bullying from older students in secondary school. Payne completed 11 GCSEs at St Peter's Collegiate School (now St Peter's Collegiate Academy) before moving on to study music technology at City of Wolverhampton College. Payne was introduced to the world of show business at the age of 12, as a member of the Pink Productions Theatre Company, appearing as Tony Manero from Saturday Night Fever. Payne had previously performed in front of a crowd of 26,000 during a Wolverhampton Wanderers football match.

Payne auditioned for the fifth series of The X Factor in 2008, at 14 years old, in front of judges Simon Cowell, Cheryl Cole, Dannii Minogue and Louis Walsh. Payne moved past the first round after performing Frank Sinatra's "Fly Me to the Moon". He was cut at the boot camp stage, but Cowell then changed his mind and asked Payne to return for the judges' houses stage. Payne was cut again during judges' houses, but was encouraged by Cowell to "come back in two years".

Payne returned to the show in 2010 for the seventh series, auditioning in front of Cowell, Cole, Walsh and guest judge Natalie Imbruglia. He sang the Michael Bublé version of "Cry Me a River". He advanced but did not progress to the "Boys" category at judges' houses. During the boot camp stage of the competition, Payne, along with Harry Styles, Niall Horan, Louis Tomlinson, and Zayn Malik, were put together to form a five-piece boy band called One Direction, to compete in the "Groups" category. The group became the last contestant eliminated on the show.
