was a of the Imperial Japanese Navy (IJN). She was laid down as the passenger liner , but was purchased by the IJN in 1941 while still under construction and converted into an aircraft carrier. Completed in May 1942, the ship participated in the Aleutian Islands Campaign the following month and in several battles during the Guadalcanal Campaign later in the year. Her aircraft were used from land bases during several battles in the New Guinea and Solomon Islands Campaigns. Jun'yō was torpedoed in November 1943 and spent three months under repair. She was damaged by several bombs during the Battle of the Philippine Sea in mid-1944, but quickly returned to service. Lacking aircraft, she was used as a transport in late 1944 and was torpedoed again in December. Jun'yō was under repair until March 1945, when work was cancelled as uneconomical. She was then effectively hulked for the rest of the war. After the surrender of Japan in September, the Americans also decided that she was not worth the cost to make her serviceable for use as a repatriation ship, and she was broken up in 1946–1947.
