German submarine U-2325 was a Type XXIII U-boat of Nazi Germany's Kriegsmarine during World War II. She was ordered on 20 September 1943, and was laid down on 29 April 1944 at Deutsche Werft, Hamburg, as yard number 479. She was launched on 13 July 1944 and commissioned under the command of Oberleutnant zur See Wolf-Harald Schüer on 3 August 1944.

Like all Type XXIII U-boats, U-2325 had a displacement of 234 tonnes (230 long tons) when at the surface and 258 tonnes (254 long tons) while submerged. She had a total length of 34.68 m (113 ft 9 in) (o/a), a beam width of 3.02 m (9 ft 11 in) (o/a), and a draught depth of3.66 m (12 ft). The submarine was powered by one MWM six-cylinder RS134S diesel engine providing 575–630 metric horsepower (423–463 kilowatts; 567–621 shaft horsepower), one AEG GU4463-8 double-acting electric motor electric motor providing 580 PS (430 kW; 570 shp), and one BBC silent running CCR188 electric motor providing 35 PS (26 kW; 35 shp).

The submarine had a maximum surface speed of 9.7 knots (18.0 km/h; 11.2 mph) and a submerged speed of 12.5 knots (23.2 km/h; 14.4 mph). When submerged, the boat could operate at 4 knots (7.4 km/h; 4.6 mph) for 194 nautical miles (359 km; 223 mi); when surfaced, she could travel 2,600 nautical miles (4,800 km; 3,000 mi) at 8 knots (15 km/h; 9.2 mph). U-2325 was fitted with two 53.3 cm (21 in) torpedo tubes in the bow. She could carry two preloaded torpedoes. The complement was 14–18 men. This class of U-boat did not carry a deck gun.

On 9 May 1945, U-2325 surrendered at Kristiansand, Norway. She was later transferred to Loch Ryan, Scotland on 29 May 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-2325 was one of 116 selected to take part in Operation Deadlight. U-2325 was towed out and sank on 28 November 1945, by gunfire from the British destroyer HMS Onslow and the Polish destroyer ORP Błyskawica.

The wreck now lies at 56°10′N 10°05′W / 56.167°N 10.083°W / 56.167; -10.083.
