SM U-151 or SM Unterseeboot 151 was a World War I U-boat of the Imperial German Navy, constructed by Reiherstieg Schiffswerfte & Maschinenfabrik at Hamburg and launched on 4 April 1917. From 1917 until the Armistice in November 1918 she was part of the U-Kreuzer Flotilla, and was responsible for sinking 37 ships.

U-151 was originally one of seven Deutschland class U-boats designed to carry cargo between the United States and Germany in 1916. Five of the submarine freighters were converted into long-range cruiser U-boats (U-kreuzers) equipped with two 15 cm (5.9 in) SK L/45 deck guns, including U-151 which was originally to have been named Oldenburg. The Type U 151 class were the largest U-boats of World War I.

U-151 was commissioned on 21 July 1917. From 21 July to 26 December 1917 she was commanded by Waldemar Kophamel who took U-151 on a long-range cruise which eventually covered a total of 12,000 miles. On 19 September 1917 U-151 claimed her first victim, the 3,104-ton French sailing ship Blanche in the Atlantic Ocean. On 2 or 12 October 1917 (sources differ), she collided with the Royal Navy Q-ship HMS Begonia in the Atlantic Ocean off Casablanca, French Morocco, sinking Begonia. On 20 November 1917 U-151 captured the steamship Johan Mjelde, and scuttled her on 26 November after transferring 22 tons of her cargo of copper.
