I-159, originally I-59, was an Imperial Japanese Navy Kaidai-class cruiser submarine of the KD3B sub-class in commission from 1930 to 1945. During World War II, she made two war patrols in the Indian Ocean, took part in the Battle of Midway, and served as a training submarine before ending the war as a kaiten suicide attack torpedo carrier. She surrendered at the end of the war and was scuttled in 1946.
