Roger Chapman (Roger Maxwell Chapman) is a British singer (born on April 8, 1942, in Leicester, England).

Roger "Chappo" Chapman is probably best known for his participation in the British progressive band Family in the late 1960s through the early 1970s and subsequently, from 1973 to 1978, in Streetwalkers, a rock/R&B band. Prior to Family he had sung with this band's precursor, the Farinas. His idiosyncratic brand of on-stage showmanship and characteristic vibrato led to him becoming a cult figure on the British rock scene. Chapman once claimed he was trying to sing like both Little Richard and especially his idol Ray Charles.

In the late 1970s Roger Chapman began a solo career and recorded his first solo album, Chappo.

In 1983, Mike Oldfield recorded the album "Crises" featuring the song "Shadow On The Wall" sung by Roger Chapman. The song turned out to be a huge hit for Mike Oldfield (along with the even more popular "Moonlight Shadow").

As other musical styles, such as Punk Rock became more popular in the UK, Chapman began to have more success in other European countries, especially Germany, where he has spent much of his time since the early 1980s, winning Artist of the Year and a Lifetime Achievement Award
