HMCS Nipigon was a Bangor-class minesweeper that served in the Royal Canadian Navy during the Second World War.

The engines produced a total of 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph).

The minesweeper's keel was laid down on 4 July 1940 by Dufferin Shipbuilding Co. at Toronto and the ship was launched on 1 October later that year.

She was commissioned into the Royal Canadian Navy on 11 August 1941 at Toronto with the pennant number J154.

She was reacquired by the Royal Canadian Navy in 1952 and refitted in preparation for active duty.
