Elvis Costello (born Declan Patrick MacManus, 25 August 1954) is an English singer-songwriter. He came to prominence as an early participant in London's pub rock scene in the mid-1970s and later became associated with the punk/New Wave genre. Steeped in word play, the vocabulary of Costello's lyrics is broader than that of most popular songs. His music has drawn on many diverse genres; one critic described him as a "pop encyclopaedia", able to "reinvent the past in his own image".

Costello has won multiple awards in his career, including a Grammy Award, and has twice been nominated for the Brit Award for Best British Male. In 2003, Elvis Costello & the Attractions were inducted into the Rock and Roll Hall of Fame. In 2004, Rolling Stone ranked Costello number 80 on their list of the 100 Greatest Artists of All Time.

Costello was born Declan Patrick MacManus in St Mary's Hospital, London, the son of Lilian Alda (née Ablett, b. 1927, Liverpool) and Ross MacManus (1927–2011), a musician and bandleader. He is of Irish heritage. Costello lived in Twickenham, attending Hounslow Secondary Modern School, which is now St Mark's Catholic Secondary School, in neighbouring Hounslow. With a musically inclined father (who was a jazz trumpeter and sang with The Joe Loss Orchestra), Costello's first broadcast recording was alongside his dad in a television commercial for R. White's Lemonade (I'm a Secret Lemonade Drinker). His father wrote and sang the song; Costello provided backing vocals. The advertisement won a silver award at the 1974 International Advertising Festival.
