The Ontario general election of 1971 was held on October 21, 1971, to elect the 117 members of the 29th Legislative Assembly of Ontario (Members of Provincial Parliament, or "MPPs") of the Province of Ontario, Canada.
The Ontario Progressive Conservative Party, led by Bill Davis, who had replaced John Robarts as PC leader and premier earlier in the year, won a ninth consecutive term in office, and maintained its majority in the legislature, increasing its caucus in the legislature by eight seats from its result in the previous election.
This election marked the first time that the provincial election was held on a Thursday. Subsequently, every provincial election has also been held on a Thursday, with the exception of the 2007 Ontario general election, which was held on a Wednesday.
