The Mark IV (pronounced Mark four) was a British tank of the First World War. Introduced in 1917, it benefited from significant developments of the Mark I tank (the intervening designs being small batches used for training).

The Panzerbefehlswagen IV (Pz. Bef. Wg. IV) was a command tank. This conversion entailed the installation of additional radio sets with associated mounting racks, transformers, junction boxes, wiring, antennas and an auxiliary electrical generator.

The Mark IV was used en masse, about 460 tanks, at the Battle of Cambrai in November 1917. The Mark V, with a much improved transmission, entered service in mid-1918. More than two thousand British heavy tanks were produced. Manufacture was discontinued at the end of the war.

The Mark IV was propelled by the Daimler-Foster, 6-cylinder in-line sleeve valve petrol engine, which developed 105 bhp at 1,000 rpm, allowing a speed of 6.4 km/h (4 mph). Transmission had 2 forward and 1 reverse primary gears and 2 speed secondary gears.

The Mark IV was the first tank to be produced and used en masse. Following the modest success of the Mark I tanks on the Somme in 1916 the British Commander-in-Chief, Sir Douglas Haig, ordered 1,000 more tanks for 1917.
