SM U-122[Note 1] was a Type UE II long-range minelayer submarine of the Imperial German Navy during World War I. U-122 was engaged in naval warfare and took part in the First Battle of the Atlantic.[3] U-122 succeeded in sinking one ship during her career for a total of 278 gross register tons (GRT).

U-122 was surrendered to the Allies at Harwich on 26 November 1918 in accordance with the requirements of the Armistice with Germany. She was later laid up at Chatham until towed out round into the English Channel and scuttled off the Isle of Wight on 1 July 1921.[4]
