Peter Charles Tabuns MPP (born October 3, 1951) is a Canadian politician who served as the interim leader of the Ontario New Democratic Party and the leader of the Official Opposition from 2022 to 2023. He is a member of the Legislative Assembly of Ontario, first elected in a 2006 by-election to represent the riding of Toronto—Danforth.

In 2009, he entered the party leadership convention but lost to Andrea Horwath. Following Horwath's resignation as leader after the 2022 Ontario general election, the Ontario New Democratic Party caucus unanimously recommended Tabuns' selection as the Ontario NDP's interim leader. His appointment was confirmed by the party's provincial council on June 28, 2022. He served until the election of his successor, Marit Stiles, following the leadership election.

Following the 2025 Ontario general election (February 27, 2025), Peter Tabuns was appointed the Official Opposition Critic for Emergency Preparedness and Response, and for Environment, Conservation, and Parks.
