SM UC-76 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 12 January 1916 and was launched on 25 November 1916. She was commissioned into the German Imperial Navy on 17 December 1916 as SM UC-76. In two patrols UC-76 was credited with sinking 15 ships, either by torpedo or by mines laid. UC-76 was surrendered on 1 December 1918 and broken up at Brighton Ferry in 1919–20.

A German Type UC II submarine, UC-76 had a displacement of 410 tonnes (400 long tons) when at the surface and 493 tonnes (485 long tons) while submerged. She had a length overall of 50.45 m (165 ft 6 in), a beam of 5.22 m (17 ft 2 in), and a draught of 3.65 m (12 ft). The submarine was powered by two six-cylinder four-stroke diesel engines each producing 290–300 metric horsepower (210–220 kW; 290–300 shp) (a total of 580–600 metric horsepower (430–440 kW; 570–590 shp)), two electric motors producing 620 metric horsepower (460 kW; 610 shp), and two propeller shafts. She had a dive time of 30 seconds and was capable of operating at a depth of 50 metres (160 ft).

The submarine had a maximum surface speed of 11.8 knots (21.9 km/h; 13.6 mph) and a submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, she could operate for 52 nautical miles (96 km; 60 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,660 to 10,230 nautical miles (16,040 to 18,950 km; 9,970 to 11,770 mi) at 7 knots (13 km/h; 8.1 mph). UC-76 was fitted with six 100 centimetres (39 in) mine tubes, eighteen UC 200 mines, three 50 centimetres (20 in) torpedo tubes (one on the stern and two on the bow), seven torpedoes, and one 8.8 centimetres (3.5 in) Uk L/30 deck gun. Her complement was twenty-six crew members.
