SM UB-116 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 24 May 1918 as SM UB-116.

UB-116 was sunk by a remote-controlled mine at 58°50′N 3°4′W / 58.833°N 3.067°W / 58.833; -3.067 off Orkney while making an attempt to enter Scapa Flow in order to attack units of the British Grand Fleet as part of the final German Naval offensive of the war.

According to Uboat.net, UB-116 hit a mine and was next finished off by depth charges while trying to reach the empty Scapa anchorage. All hands were lost (36 sailors).
