Colin James Bailey (born 9 July 1934) is British-born American jazz drummer.

Born in Swindon, England in 1934, Bailey learned to play drums as a child, studying formally from age seven. His first band was the Nibs, when he was 7, which consisted of two accordions, banjo and drums. He toured with Winifred Atwell from 1952-1956, and performed at the London Palladium for Queen Elizabeth (1952). He lived in Australia from 1958 into the early 1960s, playing in the staff band for Channel 9 TV. In Sydney he played with Bryce Rohde and the Australian Jazz Quartet, backing musicians such as Dizzy Gillespie and Sarah Vaughan. When the AJQ toured the U.S., Bailey was hired by Vince Guaraldi, with Monty Budwig on bass. This trio played with Jimmy Witherspoon, Ben Webster, and Gene Ammons for the Jazz Workshop in San Francisco.
