The Neptune class was a proposed class of cruisers planned for the British Royal Navy in the latter years of the Second World War. They were large ships which were to be armed with twelve 6-inch (152 mm) dual-purpose guns and with a heavy secondary armament. Although five ships of the class were planned in 1944, they were cancelled following the end of the war and before construction could begin.
