The Battle of Miyako Bay (宮古湾海戦, Miyako-wan Kaisen) was a naval action on 6 May 1869, in which samurai loyalists of the former Tokugawa shogunate under the flag of the newly formed Republic of Ezo failed to take over the Kōtetsu, the flagship of the Imperial forces of the new Meiji government. It was part of the overall Battle of Hakodate at the end of the Boshin War.
