The 1970 Quebec general election was held on April 29, 1970, to elect members of the National Assembly of Quebec. The former Legislative Assembly had been renamed the "National Assembly" in 1968. The Quebec Liberal Party, led by Robert Bourassa, defeated the incumbent Union Nationale, led by Premier Jean-Jacques Bertrand.

The National Assembly of Quebec is the legislative body of the province of Quebec in Canada. Legislators are called MNAs. The lieutenant governor of Quebec and the National Assembly compose the Legislature of Quebec, which operates in a fashion similar to those of other Westminster-style parliamentary systems. The assembly has 125 members elected first past the post from single-member districts.
