The 31st National Assembly of Quebec was the provincial legislature in Quebec, Canada that was elected in the 1976 Quebec general election. It sat for six sessions from 14 December 1976 to 23 December 1976; from 8 March 1977 to 22 December 1977; from 21 February 1978 to 20 February 1979; from 6 March 1979 to 18 June 1980; on 24 October 1980 (one day); and from 5 November 1980 to 12 March 1981. The Parti Québécois led by René Lévesque came to power for the first time, and organized the 1980 Quebec sovereignty referendum, which resulted in a win for the "no" side. The Quebec Liberal Party opposition was led by interim leader Gérard D. Levesque and later by Claude Ryan.
