In Canadian English, a Québécois (IPA: /kebe'kwa/), or in the feminine Québécoise (IPA: /kebe'kwaz/), is a francophone native or resident of the province of Quebec, Canada. The term may also refer to a Quebecker who identifies with Quebec's French-speaking majority culture or someone of French-Canadian descent.
With a lower-case initial, the word québécois can refer to Quebec French, a variant of the French language spoken by over 90 percent of Quebec's population. As an adjective, it refers to Quebec's francophone culture or population.
In French, the word Québécois generally refers to a native or resident of Quebec or of Quebec City. Its English equivalent is Quebecer or Quebecker (pronounced [kwəˈbɛkɚ] or [kəˈbɛkɚ]). These terms generally refer to any resident of Quebec, including anglophone or allophone natives or residents of Quebec. In a political or cultural context, it may take on the same meaning as the English definition of the word.
The word is featured in the Parti Québécois and Bloc Québécois political party names.
