Alan Henry Finger (6 December 1909 – 24 January 1985) was an Australian medical practitioner and a member of the Communist Party of Australia.
He was born in Dandenong, Victoria, to farmer Philip Charles Henry Finger and Minnie, née Freeman.
Finger married Joan Mary Hardiman, a journalist active in the Communist Party, on 8 December 1934.
He contested state and federal elections consistently between 1943 and 1967, but after Nikita Khrushchev's 1956 revelations about Joseph Stalin's government he focused more on issues such as the peace movement.
In 1949, after returning to Pennington in Adelaide, he married Jean Isobel Sams, née Marshall, a fellow divorcee, on 12 December.
