The Fifteenth Canadian Ministry was the cabinet chaired by Prime Minister R. B. Bennett. It governed Canada from 7 August 1930 to 23 October 1935, including only the 17th Canadian Parliament. The government was formed by the old Conservative Party of Canada.

The 17th Canadian Parliament was in session from 8 September 1930, until 14 August 1935. The membership was set by the 1930 federal election on 28 July 1930, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1935 election.
