The MG 151 is a German autocannon produced by Mauser during World War II. It was initially designed as a 15mm cannon, but was quickly redesigned to 20mm; the latter was designated MG 151/20, with the original retroactively designated MG 151/15. The MG 151/20 inherited the powerful minengeschoss explosive shell (just the projectile, not the whole cartridge) from the earlier MG FF/M and became a staple of Luftwaffe aircraft during the war, primarily as fixed offensive armament in fighters, but also in flexible defensive positions.

The MG 151/20 was also used by Italy, equipped on a number of their late-war fighter aircraft, by the Japanese on nearly 400 of their Ki-61 fighters, as well as the Romanian IAR 81. The French also made use of leftover MG 151s after the war.

Originally, the weapon was designed for the 15x96mm cartridge, so its name "MG" refers to the German term for machine gun "MaschinenGewehr" and the number 151 refers to the caliber and model. This is 1 weapon model in 15mm caliber. The MG 131 has a similar name (1 weapon model in 13 mm caliber). Despite the later change of the weapon's caliber to 20 mm, the name was not changed and it is still referred to as a Machine Gun and not an Automatic Cannon. According to German naming standards, the weapon should be called MK 20x, "MK" refers to the German term for automatic cannons "MaschinenKanone". Due to the fact that the weapon did not differ much mechanically when using a larger caliber, it was decided to leave the original name of the weapon and add a number specifying the caliber.
