SM U-13[a] 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.[1]

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.[2] 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,[1] 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.
