Edgar R. Leduc (February 4, 1888 – October 13, 1973) was a Canadian sportsman and politician.
He later worked as an insurance broker, and in 1918 became a local politician in Lachine, Quebec.
He was re-elected as a Liberal party candidate in the 1953 federal election, when his riding was changed to Jacques-Cartier—Lasalle.
After completing his only full term in the 22nd Canadian Parliament, Leduc was defeated in the 1957 election by Robert John Pratt of the Progressive Conservative party.
Leduc made another unsuccessful attempt to unseat Pratt in the 1958 election.
