The Robarts Ministry was the combined cabinet (formally the Executive Council of Ontario) that governed Ontario from November 8, 1961, to March 1, 1971.

It was led by the 17th Premier of Ontario, John Robarts.

The ministry was made up of members of the Progressive Conservative Party of Ontario, which commanded a majority of the seats in the Legislative Assembly of Ontario throughout its duration.

The ministry replaced the Frost ministry following the resignation of Premier Leslie Frost and the 1961 PC leadership convention.

Robarts resigned in 1971 and was succeeded as Premier of Ontario by Bill Davis.
