Benjamin Theaker Parkin (21 April 1906 – 3 June 1969) was a British teacher and politician who served as Member of Parliament for Stroud and for Paddington North. His father, Captain B. D. Parkin, was headmaster of Stonehouse Council School in Gloucestershire from 1912 to 1939 and Chairman of Stonehouse Parish Council.
Shortly before the end of the war Parkin was elected to Parliament for the Labour Party at the 1945 general election, becoming the first ever Labour MP for Stroud. He was on the left of the party and was part of a delegation of Labour MPs who met Joseph Stalin in 1947; when he voted against the Ireland Bill, he was warned by the Chief Whip about his conduct.
