John Graham Mitchell (9 July 1946 – 12 November 2008) was an English drummer, and actor who was best known for his work in the Jimi Hendrix Experience. He was inducted into the Modern Drummer Hall of Fame in 2009.

Mitchell was born in Ealing, Middlesex, to Phyliss C (née Preston) and Thomas J Mitchell. Mitchell and some writers note his birthdate as 9 July 1946, although several others incorrectly indicate that he was born in 1947. As a teenager, he starred in a children’s television programme, Jennings at School, and starred in a leading role in the 1960 British film Bottoms Up with Jimmy Edwards. Mitchell became a musician through working at Jim Marshall‘s drum shop on Saturdays while still at school. One of his first bands was the Soul Messengers, formed at the Ealing Club with saxophonist Terry Marshall, son of Jim Marshall. Early in his career, he gained considerable musical experience as a touring and session musician, working with Pete Nelson and the Travellers, Frankie Reid and the Casuals (1962), Johnny Harris and the Shades, the Pretty Things, Bill Knight & the Sceptres, the Riot Squad, and the Who as a session drummer while the band was in the process of replacing Doug Sandom with Keith Moon. In 1965, he also temporarily replaced Viv Prince as drummer in the Pretty Things.
