Zuihō,"fortunate phoenix" was a light aircraft carrier of the Imperial Japanese Navy. During the Second World War, she participated in many operations, including the battles of Santa Cruz, Philippine Sea and Leyte Gulf where she was finally sunk by American aircraft.

Zuihō was first laid down as the high-speed oiler Takasaki in 1934 and later redesigned as a submarine tender. As the Japanese became aware of the importance of carrier aviation, the Takasaki was converted in January 1940 to an aircraft carrier and renamed Zuihō. Zuihō was the sister ship of Shōhō, which was sunk by US aircraft at the Battle of the Coral Sea. Her aircraft complement consisted of 16 Mitsubishi A5M "Claude" fighters and 14 Nakajima B5N1 "Kate" torpedo bombers.
