Quebec nationalism or Québécois nationalism is a feeling and a political doctrine that prioritizes cultural belonging to, the defence of the interests of, and the recognition of the political legitimacy of the Québécois nation. It has been a movement and a central issue in Quebec politics since the beginning of the 19th century. Québécois nationalism has seen several political, ideological and partisan variations and incarnations over the years.

The Quebec sovereignty movement is a political movement whose objective is to achieve the independence of Quebec from Canada. Sovereignists suggest that the people of Quebec make use of their right to self-determination – a principle that includes the possibility of choosing between integration with a third state, political association with another state or independence – so that Québécois, collectively and by democratic means, give themselves a sovereign state with its own independent constitution.
