The 1921 Canadian federal election was held on December 6, 1921, to elect members of the House of Commons of Canada of the 14th Parliament of Canada. The Union government that had governed Canada through the First World War was defeated, and replaced by a Liberal government under the young leader William Lyon Mackenzie King. A new third party, the Progressive Party, won the second most seats in the election.

Thomas Alexander Crerar was a western Canadian politician and a leader of the short-lived Progressive Party of Canada. He was born in Molesworth, Ontario, and moved to Manitoba at a young age.
