The Peterson ministry was the combined cabinet (formally the Executive Council of Ontario) that governed Ontario from June 26, 1985, to October 1, 1990. It was led by the 20th Premier of Ontario, David Peterson. The ministry was made up of members of the Ontario Liberal Party, which commanded a first a minority and later a majority in the Legislative Assembly of Ontario.
The ministry replaced the Miller ministry following the 1985 Ontario general election, which resulted in the Progressive Conservative Party of Ontario winning a plurality of seats, but ultimately failing to secure the confidence of the legislature. The Peterson ministry governed through most of the 33rd Parliament of Ontario and all of the 34th Parliament of Ontario.
After the New Democratic Party secured a majority in the 1990 Ontario general election, Peterson resigned, and was succeeded as Premier of Ontario by Bob Rae.
