SM U-14 was one of the 329 submarines serving in the Imperial German Navy in World War I.

U-14 was engaged in the naval warfare and took part in the First Battle of the Atlantic. U-14 was damaged by an air raid on the German-occupied port of Zeebrugge, Belgium, on the night of 12 February 1915.

On 5 June 1915, U-14 approached the trawler Oceanic II off Peterhead, firing a couple of warning shots, but Oceanic II was armed and was acting as a decoy and returned fire, being joined by the armed trawler Hawk. U-14 was hit several times, and, unable to escape by submerging, sank, with six officers and 21 ratings being rescued, and one man, her commanding officer, being killed.
