Stewart Armstrong Copeland was born in Alexandria, Virginia on July 16, 1952, the youngest of four children of CIA officer Miles Copeland, Jr. and Scottish archaeologist Lorraine Adie. The family moved to Cairo, Egypt, a few months after his birth, and Copeland spent his formative years in the Middle East. In 1957, his family moved to Beirut, Lebanon, and Copeland attended the American Community School there. He started taking drum lessons at age 12 and was playing drums for school dances within a year.

In late 1976, Copeland founded the Police with lead singer-bass guitarist Sting and guitarist Henry Padovani (who was soon replaced by Andy Summers), and they became one of the top bands of the 1980s. The Police's early track list was mostly made of Copeland's compositions, including the band's first single "Fall Out" (Illegal Records, 1977) and the B side "Nothing Achieving". Though Copeland's songwriting contribution was reduced to a couple of songs per album as Sting started writing more material, he continued to co-arrange all the Police's songs with his two bandmates. Amongst Copeland's most notable songs are "On Any Other Day" (where he sang lead vocals too), "Does Everyone Stare" (later to be used as the title of his documentary on the band Everyone Stares: The Police Inside Out), "Contact", "Bombs Away", "Darkness" and "Miss Gradenko". Copeland also co-wrote a number of songs with Sting, including "Peanuts", "Landlord", "It's Alright for You" and "Re-Humanize Yourself".  Copeland also recorded under the pseudonym Klark Kent, releasing several UK singles in 1978 with one ("Don't Care") entering the UK Singles Chart that year, along with an eponymously titled 10-inch album on green vinyl released in 1980. Recorded at Nigel Gray's Surrey Sound Studio, Copeland played all the instruments and sang the lead vocals himself. Kent's "Don't Care", which peaked at #48 UK in August 1978, actually predates the first chart single by the Police by several months ("Can't Stand Losing You", issued in October 1978) as "Don't Care" was released in early June 1978. In 1982 Copeland was involved in the production of a WOMAD benefit album called Music and Rhythm. Copeland's score for Rumble Fish secured him a Golden Globe nomination in 1983. The film, directed and produced by Francis Ford Coppola from the S. E. Hinton novel, also had a song released to radio on A&M Records "Don't Box Me In" (UK Singles Chart n. 91)--a collaboration between Copeland and singer/songwriter Stan Ridgway, leader of the band Wall of Voodoo--that received significant airplay upon release of the film that year.  The Police stopped touring in 1984, and during this brief hiatus he released a solo album, The Rhythmatist. The record was the result of a pilgrimage to Africa and its people, and it features local drums and percussion, with more drums, percussion, other musical instruments and occasional lead vocals added by Copeland. The album was the official soundtrack to the movie of the same name, which was co-written by Stewart. He also starred in the film, which is "A musical odyssey through the heart of Africa in search of the roots of rock & roll." (Copeland is seen playing the drums in a cage with lions surrounding him.)  The band attempted a reunion in 1986, but the project fell apart.
