The 8.8 cm SK L/30 (SK - Schnelladekanone (quick loading cannon) L - Länge (with a 30-caliber barrel) was a German naval gun that was used in World War I on a variety of mounts.

The 8.8 cm SK L/30 gun weighed 644 kilograms (1,420 lb) and had an overall length of about 2.64 meters (8 ft 8 in). It used the Krupp horizontal sliding block, or "wedge", as it is sometimes referred to, breech design. In addition to mounts for surface ships there was also a submarine version which was on either a retractable or fixed pivot mount. The Krupp mount retracted vertically through a hatch, while the Erhardt version folded down onto the ship's deck.^[1]

The 8.8 cm SK L/30 was a widely used naval gun on World War I pre-dreadnoughts, cruisers, coastal defence ships, avisos, submarines and torpedo boats in both casemates and turrets. Its primary use on pre-dreadnoughts, cruisers and coastal defence ships was as an anti-torpedo boat gun, while on avisos, submarines and torpedo boats it was their secondary armament.
