German submarine U-869 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II, whose wreck was discovered off the coast of New Jersey in 1991. Its keel was laid down 5 April 1943 by Deutsche Schiff- und Maschinenbau AG Weser of Bremen. It was commissioned on 26 January 1944 with Kapitänleutnant Helmuth Neuerburg in command. Neuerburg went down with his boat.

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-869 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
