The Progressive Conservative Party of Ontario (PC; French: Parti progressiste-conservateur de l'Ontario), often shortened to the Ontario PC Party, or simply the PCs, colloquially known as the Tories, is a centre-right political party in Ontario, Canada.

During its uninterrupted governance from 1943 to 1985, the Ontario PC Party adhered to the ideology of Red Toryism, favouring government intervention in the economy, increased spending on infrastructure, education and health care and being progressive on social issues such as equal pay for women, anti-discrimination laws, voting rights for First Nations people and French-language services. In the 1990s, the party underwent a shift to Blue Toryism after the election of Mike Harris as leader, who was premier from 1995 to 2002 and favoured a "Common Sense Revolution" platform of cutting taxes and government spending while balancing the budget through small government. The PCs lost power in 2003; however, they came back to win a majority government in 2018 under Doug Ford. They were reelected in 2022 and 2025.
