List of New Democratic Party first ministers

The New Democratic Party (NDP) is a Canadian social democratic political party. The NDP contests both federal elections, and provincial elections in ten of Canada's thirteen provinces and territories. Unlike most other political parties in Canada, the NDP's constitution defines their provincial and territorial counterparts to be affiliates or wings of the same greater political party, rather than independent organizations with a common name.^[1]

The NDP has yet to form government at the federal level, but have won at least one election in six provinces and one territory since its establishment. This article is a list of all New Democratic leaders that have served as the prime minister of Canada or a premier in a Canadian province or territory. This list also includes first ministers of the Co-operative Commonwealth Federation, the predecessor to the NDP.
