SM UC-14 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 23 November 1914, laid down on 28 January 1915, and was launched on 13 May 1915. She was commissioned into the German Imperial Navy on 5 June 1915 as SM UC-14. Mines laid by UC-14 in her 38 patrols were credited with sinking 16 ships, one of which was the Italian pre-dreadnought battleship Regina Margherita, which at 13,427 tonnes (13,215 long tons) displacement was one of the largest ships sunk by U-boats during the war. UC-14 was mined and sunk on 3 October 1917.

The submarine's wreck was finally located in September 2023
