Quebec nationalism or Québécois nationalism is a political ideology 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.
Quebec nationalism plays a central role in the political movement for the independence of Quebec from Canada. Several groups and political parties claim to be Québécois nationalists. The autonomist political parties, which do not want the sovereignty of Quebec but the expansion of its powers and the defence of its specificity within Canada, such as the Coalition Avenir Québec, also claim to be Québécois nationalists.
