SMS G39 was a 1913 Type Large Torpedo Boat (Großes Torpedoboot) of the Imperial German Navy (Kaiserliche Marine) during World War I, and the 15th ship of her class.

Built by Germaniawerft in Kiel, Germany, she was commissioned in August 1915.

G39 was assigned to the High Seas Fleet of the Kaiserliche Marine when she participated in the Battle of Jutland.

After the end of hostilities, G39 was interned at Scapa Flow and scuttled.

One of the crew members on her last voyage was Leopold Bürkner, who later became head of foreign affairs intelligence during the Third Reich.
