Gédéon Ouimet (June 2, 1823 – April 23, 1905) was a French-Canadian politician.

Born in what is today part of the city of Laval, Quebec Canada, Ouimet served as the second premier of Quebec from February 26, 1873 to September 22, 1874.

He resigned as party leader of the Conservative Party of Quebec in 1874 because of the Tanneries scandal which implicated the government of Quebec.

The Quebec town of Grandmont changed its name to Saint-Gédéon in honour of Ouimet.

It connects the municipality of Laval to the northern shore in what is now known as the town of Boisbriand.
