The Parti Québécois (French: Parti québécois, PQ; pronounced: [pa%CA%81.ti ke.be.kwa]) is a sovereignist provincial political party in Quebec in Canada. The PQ advocates national sovereignty for Quebec involving independence of the province of Quebec from Canada and establishing a sovereign state. The PQ has promoted the possibility of maintaining a loose political and economic sovereignty-association between Quebec and Canada. The party traditionally has support from the labour movement, but unlike most other social-democratic parties, its ties with the labour movement are informal.[7] Members and supporters of the PQ are called "péquistes", a French word derived from the pronunciation of the party's initials.

Pierre Karl Péladeau was elected party leader on May 15, 2015. The party is an observer member of COPPPAL. The party has strong informal ties to the Bloc Québécois (BQ, whose members are known as "Bloquistes"), the federal party that advocates for the secession of Quebec from Canada and its independence, but the two are not linked organizationally. As with its federal counterpart, the Parti Québécois has been supported by a wide range of voters in Quebec, from large sections of organised labour to more conservative rural voters.
