SM U-13 was one of 329 U-boats which served in the Imperial German Navy during World War I.

The first of three submarines of the gasoline powered Type U 13 class, the boat was ordered in February 1909 and built at Kaiserliche Werft Danzig. It was launched in December 1910 and commissioned into the Imperial German Navy on 25 April 1912.

At the start of World War I U-13 was commanded by Kapitänleutnant Hans Arthur Graf von Schweinitz und Krain, a career officer who had joined the Navy in 1902. The boat left port at Heligoland in early August 1914 as part of a coordinated attack by U-boats on the British naval base at Scapa Flow. The boat was not heard from again. She is recorded as having been lost between 6 and 12 August, and may have been a victim of the German defensive minefield in the Heligoland Bight, or been sunk due to an accident or mechanical failure. All of the crew were lost.
