German submarine U-89 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She was laid down at the Flender Werke in Lübeck as yard number 293, launched on 20 September 1941 and commissioned on 19 November with Kapitänleutnant Dietrich Lohmann in command.

She was a fairly successful boat, sinking over 13,000 tons of Allied shipping in a career lasting just one year and five patrols. She was a member of ten wolfpacks. After training with the 8th U-boat Flotilla, U-89 was assigned to the 9th flotilla on 1 May 1942 for operations.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-89 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 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 AEG GU 460/8–27 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).
