The Maschinengewehr 08, or MG 08, was the German Army's standard machine gun in World War I and is an adaptation of Hiram S. Maxim's original 1884 Maxim gun. It was produced in a number of variants during the war. The MG 08 served during World War II as a heavy machine gun in many German infantry divisions, although by the end of the war it had mostly been relegated to second-rate fortress units.

The Maschinengewehr 08 (or MG 08)—so-named after 1908, its year of adoption—was a development of the license made Maschinengewehr 01. The firing rate depends on the lock assembly used and averages 500 rounds per minute for the Schloss 08 and 600 rounds per minute for the Schloss 16. The gun used 250-round fabric belts of 7.92×57mmammunition, although sustained firing would lead to overheating; it was water-cooled using a jacket around the barrel that held approximately one gallon of water. Using a separate attachment sight with range calculator for indirect fire, the MG 08 could be operated from cover. Additional telescopic sights were also developed and used in quantity during the war.

The MG 08, like the Maxim gun, operated on the basis of short barrel recoil and a toggle lock; once cocked and fired the MG 08 would continue firing rounds until the trigger was released (or until all available ammunition was expended). Its practical range was estimated at some 2,000 metres (2,200 yd) up to an extreme range of 3,600 metres (3,900 yd). The MG 08 was mounted on a sled mount (German: Schlittenlafette) that was ferried between locations either on carts or else carried above men's shoulders in the manner of a stretcher.

Pre-war production was by Deutsche Waffen und Munitionsfabriken (DWM) in Berlin and the government arsenal at Spandau (so that the gun was often referred to as a Spandau MG 08). When the war began in August 1914, approximately 12,000 MG 08s were available to battlefield units; production, at numerous factories, was however markedly ramped up during wartime. In 1914 some 200 MG 08s were produced each month; by 1916—once the weapon had established itself as the pre-eminent defensive battlefield weapon—the number had increased to 3,000; and a year later to 14,400 per month.
