German submarine U-2545 was a Type XXI U-boat of Nazi Germany's Kriegsmarine during World War II.

The Elektroboote submarine was laid down on 20 November 1944 at the Blohm & Voss yard at Hamburg, launched on 22 February 1945, and commissioned on 8 April 1945 under the command of Korvettenkapitän Otto von Bülow.

U-2545 was a brand new, high technology electric boat which could run constantly submerged rather than having to surface to recharge her batteries every day the way submarines until that point had had to do.

The exception to this were the new Type XXI boats, which continued to train in the Baltic Sea.
