SM U-152 was a German Type U 151 submarine of the Imperial German Navy during World War I.

Built at Hamburg, the submarine was commissioned in October 1917. Initially intended as a submersible merchantman for transporting critical war through the British blockade, she was converted to a combat ship while under construction.

U-152 was actively employed in the Atlantic during the last year of the conflict. Among her victims were two American schooners, Julia Frances (sunk on 27 January 1918) and A.E. Whyland (sunk on 13 March 1918), the Norwegian barque Stifinder (boarded and scuttled on 13 October 1918), the Spanish Giralda (sunk on 25 January 1918), and the U.S. Navy cargo ship USS Ticonderoga. The latter was sunk, after a two-hour gun battle, with heavy casualties among her crew and passengers, on 30 September 1918. The previous day, 29 September, the submarine had also fought a gun battle with the Navy oiler USS George G. Henry, but despite being badly damaged the American ship escaped.

After returning to Germany in November 1918, at the end of her final wartime cruise, U-152 went to Harwich, England, where she was surrendered to the British. U-152 was deliberately sunk by the Royal Navy in July 1921.
