SM UC-24 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 29 August 1915 and was launched on 4 March 1916. She was commissioned into the German Imperial Navy on 15 August 1916 as SM UC-24. In four patrols UC-24 was credited with sinking 4 ships, either by torpedo or by mines laid. UC-24 was torpedoed and sunk by Circé off Cattaro on 24 May 1917. The wreck was found in late 2019 at a depth of 85m, 2 nautical miles from the mainland (Molunat, Dubrovnik, today's Croatia).
