SM UB-88 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 26 January 1918 as SM UB-88.

She was built by AG Vulcan of Hamburg and following just under a year of construction, launched at Hamburg on 11 December 1917. UB-88 was commissioned early the next year under the command of Oblt.z.S. Johannes Ries. Like all Type UB III submarines, UB-88 carried 10 torpedoes and was armed with a 10.5 cm (4.13 in) deck gun. UB-88 would carry a crew of up to 3 officers and 31 men and had a cruising range of 7,120 nautical miles (13,190 km; 8,190 mi). UB-88 had a displacement of 510 t (500 long tons) while surfaced and 640 t (630 long tons) when submerged. Her engines enabled her to travel at 13 knots (24 km/h; 15 mph) when surfaced and 7.4 knots (13.7 km/h; 8.5 mph) when submerged.

UB-88 was surrendered to the United States of America on 26 November 1918 in accordance with the requirements of the Armistice with Germany.

After an extensive tour along the U.S. coast, she was sunk as a target on 3 January 1921 in waters off Los Angeles County, California. The wreck of the vessel was found in 2003.
