The Manitoba Social Credit Party (originally the Manitoba Social Credit League) was a political party in the Canadian province of Manitoba. In its early years, it espoused the monetary reform theories of social credit. It was formed in the 1935-1936, shortly after William Aberhart's supporters formed a Social Credit government in Alberta. While the party never won many seats in the Legislative Assembly of Manitoba, it maintained a presence in the legislature for most of the period from 1936 to 1973.
