'Pitchbowl' was a British naval undertaking against U-boats operating in the North-Western Approaches to the UK (13/15 April 1944).

The escort carriers Emperor, Pursuer and Fencer, the heavy cruiser Berwick, the light anti-aircraft cruiser Royalist, cruiser Sheffield, and the destroyers Musketeer, Meteor, Marne, Matchless, Onslaught, Polish Piorun and Canadian Sioux sortied from Scapa Flow in the Orkney islands group on 13 April, and returned two days later after the operation had been called off as a result of adverse weather conditions.
