Charles-Eugène Marin (29 October 1925 – 7 June 2017) was a member of the House of Commons of Canada.
Born in Ste-Anne-des-Monts, Quebec, he was a physician and psychiatrist by career.
He represented the Quebec riding of Gaspé where he was first elected in the 1984 federal election and re-elected in 1988, therefore becoming a member in the 33rd and 34th Canadian Parliaments.
He was a member of the Progressive Conservative party.
In the 1993 federal election, Marin was defeated by Yvan Bernier of the Bloc Québécois and therefore left federal politics.
