HMCS Clayoquot was a Bangor-class minesweeper that served with 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).

[4] Clayoquot was armed with a single quick-firing (QF) 4-inch (102 mm)/40 caliber Mk IV gun mounted forward.

[3] She left Esquimalt, British Columbia after working up and made her way to Halifax, Nova Scotia where she arrived on 14 November 1941.

During depth charge attacks on possible targets, Clayoquot's radio was knocked out and prevented the ship from informing command of the corvette's loss.

In January 1944 she was assigned to HMCS Cornwallis as an officer training vessel for anti-submarine warfare.

[3] While sweeping for submarines near Sambro Island Light on 24 December 1944 in preparation to escort a convoy, Clayoquot was hit aft by a torpedo fired by U-806.

There had not been enough time to disarm the depth charges kept ready, which detonated as the ship sank causing injuries among the surviving crew, which were picked up by the corvette Fennel.
