The last battle of the German battleship Bismarck took place in the Atlantic Ocean approximately 300 nautical miles west of Brest, France, on 26–27 May 1941 between the German battleship Bismarck and naval and air elements of the British Royal Navy. Although it was a decisive action between capital ships, it has no generally accepted name. It was the culmination of Operation Rheinübung where the attempt of two German ships to disrupt the Atlantic Convoys to the United Kingdom failed with the scuttling of the Bismarck.

Bismarck was the first of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine. Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.
