Graham Parker (born 18 November 1950 in London, England) is a British rock singer and songwriter who is best known as the lead singer of popular British New Wave band Graham Parker & the Rumour.

In the late 1960s and early 1970s, Graham Parker sang in small-time English bands such as the Black Rockers and Deep Cut Three while working in dead-end jobs like a glove factory and a petrol station. In 1975, he recorded a few demo tracks in London with Dave Robinson, who would shortly found Stiff Records and who connected Parker with his first backing band of note, The Rumour. Graham Parker had one track, "Back to Schooldays", released on the compilation album, A Bunch of Stiff Records for Stiff Records.

In the summer of 1975 Parker joined forces with ex-members of three British pub-rock bands to form Graham Parker and the Rumour. The new group consisted of Parker (lead vocals, guitar) with Brinsley Schwarz (lead guitar) and Bob Andrews (keyboards) (both ex Brinsley Schwarz), Martin Belmont (rhythm guitar, ex Ducks Deluxe) and Andrew Bodnar (bass) and Steve Goulding (drums) (both ex-Bontemps Roulee). They began doing the rounds of the British pub rock scene, often augmented at times by a four-man horn section known as The Rumour Brass: John "Irish" Earle (saxophone), Chris Gower (trombone), Dick Hanson (trumpet), and Ray Bevis (saxophone).
