The 1990 Ontario general election was held on September 6, 1990, to elect members of the 35th Legislative Assembly of the province of Ontario, Canada. The governing Ontario Liberal Party led by Premier David Peterson was unexpectedly defeated. Although the Peterson government, and Peterson himself, were very popular, he was accused of opportunism in calling an election just three years into his mandate. In a shocking upset, the New Democratic Party (NDP), led by Bob Rae, won a majority government. This marked the first time the NDP had won government east of Manitoba, and to date the only time the NDP formed the government in Ontario.

Not even the NDP expected to come close to winning power. Rae had already made plans to retire from politics after the election; however, the NDP managed to take many seats in the Greater Toronto Area (GTA) from the Liberals, and Rae himself represented York South, in Metro Toronto. They also did better than ever before, or in some cases since, in many other cities and rural areas. The NDP finished only five points ahead of the Liberals in the popular vote, but due to the nature of the first-past-the-post electoral system, which ignores the popular vote and awards power based on the number of ridings won, the NDP's gains in the GTA decimated the Liberal caucus. The Liberals lost 59 seats, the second-worst defeat for a governing party in Ontario. At the time, it was the Liberals' worst showing in an Ontario election. Peterson himself was heavily defeated in London Centre by NDP challenger Marion Boyd, losing by 8,200 votes, one of the few times a provincial premier has lost their own seat.

Although Mike Harris' Progressive Conservative Party was unable to overcome voter distrust of the federal Progressive Conservative government of Brian Mulroney, his party managed to make a net gain of four seats. Although Harris was from northern Ontario, the Tories were particularly weak in that region, placing fourth, behind the Liberals, NDP, and the right-wing Confederation of Regions Party (CoR) in six northern Ontario ridings (Algoma, Cochrane South, Nickel Belt, Sudbury, Sudbury East, and Sault Ste. Marie). The CoR also placed ahead of the Progressive Conservatives in the Renfrew North and Cornwall ridings in eastern Ontario. Although they received only 1.9% of the vote provincewide, they managed 7.8% in the 33 ridings in which they actually fielded a candidate.

The Green Party of Ontario placed third, ahead of the NDP, in Parry Sound riding, where former Liberal leadership candidate Richard Thomas was the party's candidate.

Riding name change

Before the election, an Act was passed, changing the name of Prince Edward—Lennox to Prince Edward—Lennox—South Hastings.
