The Kii-class battleship (Japanese: 紀伊型戦艦, romanized: Kii-gata senkan, lit. 'Era') was a planned class of four fast battleships to be built for the Imperial Japanese Navy (IJN) during the 1920s. Only two of the ships received names. They were intended to reinforce Japan's "eight-eight fleet" of eight battleships and eight battlecruisers after the United States announced a major naval construction program in 1919. However, after the signing of the Washington Naval Treaty in 1922, work on the ships was suspended; one pair was cancelled in November 1923 and the other in April 1924.
