The Fairmile C motor gun boat was a type of motor gunboat designed by Norman Hart of Fairmile Marine for the Royal Navy. An intermediate design, twenty-four boats were ordered on 27 August 1940 from Fairmile Marine in kit form and were assembled at multiple boatbuilders' yards and completed in 1941; they were initially rated as Motor Launches (ML), but received the designation Motor Gun Boats (MGB) on 1 August 1941, being numbered MGB 312–335.
