SM UB-89 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 25 February 1918 as SM UB-89.[Note 1]
UB-89 was lost in a collision with the light cruiser SMS Frankfurt in Kiel. Seven crew members perished in the accident. On 30 October 1918 the boat was raised by the salvage ship SMS Cyclop.
