The Tenth Canadian Ministry was the second cabinet chaired by Prime Minister Sir Robert Borden. It governed Canada from 12 October 1917 to 10 July 1920, including most of the 13th Canadian Parliament. The government was formed by the Unionists, a war-time coalition between the old Conservative Party of Canada and some members of the Liberal Party of Canada. Borden was also Prime Minister in the Ninth Canadian Ministry, but formed a coalition ministry for the 1917 Canadian federal election.

The 13th Canadian Parliament was in session from March 18, 1918, until October 4, 1921. The membership was set by the 1917 federal election on December 17, 1917, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1921 election.
