HMCS Fort Frances was an Algerine-class minesweeper that served in the Royal Canadian Navy during the Second World War. She served primarily as a coastal convoy escort in the Battle of the Atlantic. The ship was named for Fort Frances, a town in northwestern Ontario. Following the war, the vessel was transferred to the Department of Mines and Technical Surveys and used for hydrographic and oceanographic survey. The vessel was discarded in 1974 and broken up for scrap.
