The Labour-Progressive Party was a Communist party in Canada.

When the Communist Party of Canada was banned in 1941, it refounded itself as the Labour-Progressive Party. The LPP only ever elected one Member of Parliament under its own banner, Fred Rose, who was elected in a 1943 by-election in Montreal and sat in the House of Commons. In 1947, he was charged and convicted for spying for the Soviet Union, and was expelled from the House of Commons.

Dorise Nielson was elected to the House of Commons in 1940 from Saskatchewan as a Progressive Unity MP, but was defeated in 1945 when she ran for re-election as an LPP candidate.

In Ontario, two LPP members, A. A. MacLeod and J. B. Salsberg, sat in the Legislative Assembly of Ontario from 1943 to 1951 and 1955 respectively. The LPP also jointly nominated several Liberal-Labour candidates with the Ontario Liberal Party.

The Manitoba party had amongst its leading members Jacob Penner who was a popular aldermen in Winnipeg, Manitoba, as well as W. A. Kardash who was a Manitoba MLA.

The party also ran candidates in Quebec general elections from 1944 to 1956 as the Parti ouvrier-progressiste.

The leader of the party was Tim Buck.

Other prominent members were Margaret Fairley and Stanley Ryerson.
