SM U-5 was a German Type U 5 submarine which served in the Imperial German Navy during World War I. Built at Germaniawerft in Kiel between 1908 and 1910, she was commissioned on 2 July 1910.

At the start of World War I U-5 was commanded by Kapitänleutnant Johannes Lemmer. The boat undertook two war patrols but did not sink any ships. In December 1918 she transferred to the Belgian port of Zeebrugge to carry out coastal patrols. She was lost in what is presumed to have been an accident close to the port on or around 18 December 1914. There were no survivors from her crew of 29.

On 4 September 2023, it was announced that the wreck of U-5 had been located close to Zeebrugge. It was found near the wreck of UC-14, also located by the same team, which was lost to mines in October 1917. The wreck of U-5 was reported as being in good condition, whereas UC-14 had clearly been impacted by an explosion.
