SM UB-2 was a German Type UB I submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She sank eleven ships during her career and was broken up in Germany in 1920.

UB-2 was ordered in October 1914 and was laid down at the Germaniawerft shipyard in Kiel in November. UB-2 was a little more than 28 metres (92 ft) in length and displaced between 127 and 142 tonnes (125 and 140 long tons), depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. She was launched and commissioned as SM UB-2 in February 1915.

When UB-2 sailed to join the Flanders Flotilla in May 1915, she became the only member of her class to not be shipped by rail to Antwerp to join the unit. While in the flotilla, UB-2 sank eleven British ships of 1,374 gross register tons (GRT) under the command of Kptlt. Werner Fürbringer. The U-boat was assigned to the Baltic Flotilla in March 1916 relegated to a training role from December that same year. At the end of the war, UB-2 was deemed unseaworthy and unable to surrender at Harwich with the rest of Germany's U-boat fleet. She remained in Germany where she was broken up by Stinnes in February 1920.
