Joseph-Théodule Rhéaume (September 13, 1874 – August 10, 1954) was a Quebec politician, lawyer and judge. Rhéaume earned his law degree at Laval University and was admitted to the bar in 1903 and became King's Counsel in 1914. He was elected by acclamation as a Liberal to the House of Commons of Canada in the riding of Jacques Cartier in a 1922 by-election. He was re-elected in the 1925 and 1926 federal elections twice defeating Esioff-Léon Patenaude who was Conservative leader Arthur Meighen's Quebec lieutenant and Justice minister. However, Rhéaume lost his seat in the 1930 federal election.
