John Cooney Mullally (28 November 1930 – 7 February 2021) was a Liberal party member of the House of Commons of Canada.
After serving only one term in office, the 26th Canadian Parliament, Mullally was defeated at King's riding in the 1965 election by Melvin McQuaid of the Progressive Conservative party.
Mullally faced McQuaid again in the 1968 federal election, that time at Cardigan because of riding boundary changes in the late 1960s.
Mullally died on 7 February 2021 at the age of 90.
