The Thirteenth Canadian Ministry was the second cabinet chaired by Prime Minister Arthur Meighen. It governed Canada from 29 June 1926 to 25 September 1926, including only the last three months of the 15th Canadian Parliament, all cabinet ministers were acting cabinet ministers as Meighen hadn't been given the confidence of the house, and any cabinet ministers appointed by him would have had to resign their seats and run for re-election. The government was formed by the old Conservative Party of Canada. Meighen was also Prime Minister in the Eleventh Canadian Ministry.

The 15th Canadian Parliament was in session from 7 January 1926, until 2 July 1926. The membership was set by the 1925 federal election on 29 October 1925, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1926 election.
