The Parti ouvrier-progressiste (English: Labor-Progressive Party) was the name under which the Parti Communiste du Québec ran candidates from 1944 to 1956, after the banning of the Communist Party of Canada in 1941. Its English counterpart was the Labor-Progressive Party, whose candidate Fred Rose was elected to the House of Commons of Canada for the riding of Cartier in 1943.

The POP took its current name, the Parti Communiste du Québec, in 1960.
