'MTM' was the designation of Allied military convoys (together with a numerical suffix) carrying motor transport from the Bay of the Seine to Southend or other southern British ports in succession to the 'FTM' series, and as such reciprocals of the 'TMM' series (October/November 1944).

Associated with the Allied land advances into Belgium and the Netherlands from the Normandy lodgement gained in 'Overlord', there were 19 such convoys between MTM.1 of 11/12 October with eight British vessels (3,625-ton Baron Renfrew, 2,922-ton Empire Ness, 7,086-ton Empire Pitt, 7,067-ton Empire Swordsman, 7,131-ton Fort Brandon, 7,129-ton Fort Carillon, 7,161-ton Fort Wallace and 7,219-ton Samnesse) and MTM.19 of 25/26 November with two British vessels (8,208-ton Gold Shell and 7,255-ton Samaustral) and the 7,176-ton US Herman Melville.
