François Gérin (3 August 1944 – 3 April 2005) was a member of the Canadian House of Commons. He was a lawyer by career.
Gérin was born in Coaticook, Quebec.
He represented the Quebec riding of Mégantic—Compton—Stanstead where he was first elected in the 1984 federal election under the Progressive Conservative party. He was re-elected in 1988, therefore becoming a member in the 33rd and 34th Canadian Parliaments.
However, he left the Progressive Conservative party on 5 May 1990 and became independent until he formally became a founding member of the Bloc Québécois in September 1991. In 1993, Gérin left federal politics and did not seek a third term in the House of Commons.
