German submarine U-86 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down at the Flender Werke in Lübeck on 20 January 1940 as yard number 282. Launched on 10 May 1941, she was commissioned on 8 July and completed training with the 5th U-boat Flotilla under the command of Kapitänleutnant (Kptlt.) Walter Schug. She was reassigned to the 1st flotilla, initially for further training on 1 September before being ready for operations from 1 December. She stayed with that organization until her loss on 29 November 1943.

U-86 completed eight war patrols with the flotilla, sinking three ships, totalling 9,614 gross register tons (GRT). She also damaged a ship of 8,627 GRT. She was a member of ten wolfpacks.

She was sunk on 29 November 1943 east of the Azores, in position 40°52'N, 18°54'W, by depth charges from two British warships, HMS Rocket (H92) and HMS Tumult (R11). 50 dead (all hands lost).

German Type VIIB submarines were preceded by the shorter Type VIIA submarines. U-86 had a displacement of 753 tonnes (741 long tons) when at the surface and 857 tonnes (843 long tons) while submerged. She had a total length of 66.50 m (218 ft 2 in), a pressure hull length of 48.80 m (160 ft 1 in), a beam of 6.20 m (20 ft 4 in), a height of 9.50 m (31 ft 2 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two MAN M 6 V 40/46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two BBC GG UB 720/8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
