'Handfast' was a British naval operation by elements of Admiral Sir Henry Moore’s Home Fleet for the aerial laying of mines in the Salhusstrommen, the strait between Karmøy and the Rogaland mainland area of German-occupied Norway (17/21 November 1944).

The ships involved were the escort carriers Premier and Pursuer, the light anti-aircraft cruiser Diadem, and the destroyers Onslaught, Scorpion, Scourge and Zealous.
