IJN Okinoshima (沖ノ島) was one of eight Russian pre-dreadnought battleships captured by the Imperial Japanese Navy during the Russo-Japanese War of 1904-1905.

The General-Admiral Graf Apraksin, an obsolete Admiral Ushakov class armored warship, optimistically classed as a coastal battleship by the Imperial Russian Navy, was captured as a prize by the Japanese Navy at the Battle of Tsushima on 28 May 1905. The Mishima (ex-Admiral Senyavin) was her sister ship, and was also captured in the same battle, whereas the lead ship of the class, Admiral Ushakov, was sunk.

The General-Admiral Graf Apraksin was commissioned into the Japanese Navy as the 2nd class Coastal Defense Vessel Okinoshima, taking her name from an island off of Munakata city, Fukuoka prefecture, which is the site of a famous Shinto shrine, and which is also geographically close to the location of the Battle of Tsushima.

On 01 April 1921, the Okinoshima was re-classified as a submarine tender.

The Okinoshima was decommissioned on 01 April 1922. It was scrapped in1925.

It should not be confused with the Pacific War era minelayer of the same name.
