Gordon Matthew Thomas Sumner (born 2 October 1951), known as Sting, is an English musician and actor. He was the frontman, principal songwriter and bassist for the rock band the Police from 1977 until their break-up in 1986. He launched a solo career in 1985 and has included elements of rock, jazz, reggae, classical, new-age, and worldbeat in his music.

Sting has sold a combined total of more than 100 million records as a solo artist and as a member of the Police. He has received three Brit Awards, including Best British Male Artist in 1994 and Outstanding Contribution to Music in 2002; a Golden Globe; an Emmy; and four Academy Award nominations. As a solo musician and as a member of the Police, Sting has received 17 Grammy Awards. He was inducted into the Rock and Roll Hall of Fame as a member of the Police in 2003. Sting has received a star on the Hollywood Walk of Fame; the Ivor Novello Award for Lifetime Achievement from the British Academy of Songwriters, Composers and Authors; a CBE from Queen Elizabeth II for services to music; Kennedy Center Honors; and the Polar Music Prize. In May 2023, he was made an Ivor Novello Fellow.

Gordon Matthew Thomas Sumner was born at Sir G B Hunter Memorial Hospital in Wallsend, Northumberland, England, on 2 October 1951, the eldest of four children of Audrey (née Cowell), a hairdresser, and Ernest Matthew Sumner, a milkman and former fitter at an engineering works. He grew up near Wallsend's shipyards, which made an impression on him. As a child, he was inspired by the Queen Mother waving at him from a Rolls-Royce to divert from the shipyard prospect towards a more glamorous life. He helped his father deliver milk and by ten was "obsessed" with an old Spanish guitar left by an emigrating friend of his father.

Sting attended St Cuthbert's Grammar School in Newcastle upon Tyne. He visited nightclubs such as Club A'Gogo to see Cream and Manfred Mann, who influenced his music. He learned to sing and play simultaneously by listening to records at 78 rpm. After leaving school in 1969, he enrolled at the University of Warwick in Coventry, but left after a term. After working as a bus conductor, building labourer, and tax officer, he attended the Northern Counties College of Education (now Northumbria University) from 1971 to 1974 and qualified as a teacher. He taught at St Paul's First School in Cramlington for two years.

Sting performed jazz in the evenings, at weekends, and during breaks from college and teaching, playing with the Phoenix Jazzmen, Newcastle Big Band and Last Exit. He gained his nickname after his habit of wearing a black and yellow jumper with hooped stripes with the Phoenix Jazzmen. Bandleader Gordon Solomon thought he looked like a bee (or according to Sting himself, "they thought I looked like a wasp"), which prompted the name "Sting". In the 1985 documentary Bring On the Night a journalist called him Gordon, to which he replied, "My children call me Sting, my mother calls me Sting, who is this Gordon character?" In 2011, he told Time "I was never called Gordon. You could shout 'Gordon' in the street and I would just move out of your way". Despite this, he chose not to legally change his name to "Sting".

In January 1977, Sting joined Stewart Copeland and Henry Padovani (soon replaced by Andy Summers) to form the Police, becoming the band's lead singer, bass player, and primary songwriter. From 1978 to 1983, the Police had five UK chart-topping albums, won six Grammy Awards and won two Brit Awards (for Best British Group and for Outstanding Contribution to Music). Their initial sound was punk-inspired, but they switched to reggae rock and minimalist pop. Their final album, Synchronicity, was nominated for five Grammy Awards including Album of the Year in 1983. It included their most successful song, "Every Breath You Take", written by Sting.

Even though logic would say, "Are you out of your mind? You're in the biggest band in the world – just bite the bullet and make some money." But there continued to be some instinct, against logic, against good advice, [that] told me I should quit.

According to Sting, appearing in the documentary Last Play at Shea, he decided to leave the Police while onstage during a concert of 18 August 1983 at Shea Stadium in New York City because he felt that playing that venue was "[Mount] Everest". While never formally breaking up, after Synchronicity, the group agreed to concentrate on solo projects. As the years went by, the band members, especially Sting, dismissed the possibility of reforming. In 2007, the band did reform temporarily for the purpose of undertaking a reunion tour.
