Lise St-Denis (born April 18, 1940) is a Canadian former politician. She was elected to the House of Commons of Canada in the 2011 election and served a single term. She was elected in the electoral district of Saint-Maurice—Champlain as a member of the New Democratic Party, but crossed the floor to the Liberal Party of Canada on January 10, 2012, saying in French to explain her move: "Voters voted for Jack Layton. Jack Layton is dead."
