This page lists the results of leadership elections within the Progressive Conservative Party of Ontario (known as the Conservative Party of Ontario before 1942).

Before 1920, leaders of the Conservative Party were usually chosen by caucus. In 1914, William Hearst was selected at a meeting of the province's executive council (or cabinet) as James Whitney, the previous leader, had died while holding the office of Premier of Ontario.

All of the party's leadership races before 1990 were determined by delegated conventions. The leadership races of 1990, 2002 and 2004 were determined by a weighted vote of all party members, with each constituency contributing an equal number of "votes" to the total. The 1990 race was decided in one round, while the 2002 race took two. For the 2004 election, the party introduced a preferential balloting system, such that party members would only be required to vote one time.
