The Algerine-class was a class of minesweepers of the Royal Navy and the Commonwealth. 110 ships of the class were launched between 1942 and 1944 and served in World War II. They were designed as small vessels that could serve in several roles, not just as minesweepers; in practice the desperate shortage of convoy escorts in the Battle of the Atlantic meant that they served mainly in that role; twelve Algerines of the Royal Canadian Navy consequently never had minesweeping gear fitted.
