SM U-88 was a Type U 87 submarine built for the Imperial German Navy (Kaiserliche Marine) in World War I. U-88 was engaged in the naval warfare and took part in the First Battle of the Atlantic.
U-88 is most notable for sinking and taking with her Kapitänleutnant Walther Schwieger, responsible for sinking the RMS Lusitania when he was commander of U-20. The submarine sank on 5 September 1917 when she presumably struck a British mine in the North Sea north of Terschelling at 53°57′N 4°55′E / 53.950°N 4.917°E. Everyone on board U-88 was killed.
