David Henry Richmond (born 29 March 1938 in Brighton, Sussex, England) is a British professional bass player, best known as a founder member of the 1960s pop group Manfred Mann. During his short tenure with the group, he played bass on their first hit record, "5-4-3-2-1". Richmond first picked up the ukulele at the age of 14. He later picked up the bass after hearing "Big Noise From Winnetka" on a record player, owned by his older brother.

Richmond joined Manfred Mann in 1963, after being recruited by Manfred Mann and Mike Hugg. Richmond left the band in 1964, shortly after he recorded bass for their track "5-4-3-2-1", a song intended as the theme for the music show Ready, Steady, Go!, which became one of Manfred Mann's earliest and biggest hits. He was replaced by Tom McGuinness. In 1966, after McGuinness had switched to lead guitar, Richmond appeared as a guest (playing double bass) on the 1966 Manfred Mann EP Instrumental Assassination.

Later on in his career, Richmond became a session player, working with musicians such as Elton John, Bread, Hank Marvin and Serge Gainsbourg, amongst many others. In the 1970s he was a member of Steve Gray's library music ensemble WASP, which recorded much music for the KPM 1000 Series. Richmond played the fretless bass guitar on the theme song to Last of the Summer Wine.
