German submarine U-804 was a Type IXC/41 U-boat of Nazi Germany's Kriegsmarine during World War II. U-804 was ordered on 7 December 1940, and was laid down on 1 December 1942 at Deutsche Schiff- und Maschinenbau AG Seebeckwerft, Bremerhaven as yard number 362. She was launched on 1 April 1943 and commissioned under the command of Oberleutnant zur See der Reserve Herbert Meyer (Crew III/37) on 4 December of that year.

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-804 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).
