Joseph-Édouard-Émile Léonard (11 December 1872 – 15 September 1933) was a Canadian lawyer and politician.

Born in Ste-Rose, Laval County, Quebec, Léonard was educated at the Colleges of Ste Therese, Joliette and St. Mary's in Montreal.

He was the Conservative candidate in the electoral district of Laval in the general elections of 1900 but was defeated by Thomas Fortin.

He was first elected to the House of Commons of Canada in a 1902 by-election, after Fortin was appointed Judge of the Superior Court of Quebec, Montreal District.
