German submarine U-98 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II, operating from March 1941 until she was sunk in November 1942.

She was launched on 31 August 1940 and commissioned on 12 October, with a crew of 46 under the command of Kapitänleutnant Robert Gysae, operating from St. Nazaire in France. In March 1942 command was transferred to Korvettenkapitän Wilhelm Schulze. Her final commander was Oberleutnant zur See Kurt Eichmann, who took over in October 1942. She was a member of six wolfpacks.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-98 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).
