Crew of the Battleship Petropavlovsk bathing.

Petropavlovsk (Russian: Петропавловск) was the lead ship of her class of three pre-dreadnought battleships built for the Imperial Russian Navy during the last decade of the 19th century. The ship was sent to the Far East almost immediately after entering service in 1899, where she participated in the suppression of the Boxer Rebellion the next year and was the flagship of the First Pacific Squadron.

At the beginning of the Russo-Japanese War of 1904–1905, Petropavlovsk took part in the Battle of Port Arthur, where she was lightly damaged by Japanese shells and failed to score any hits in return. On 13 April 1904, the ship sank after striking one or more mines near Port Arthur, in northeast China. Casualties numbered 27 officers and 652 enlisted men, including Vice Admiral Stepan Makarov, the commander of the squadron, and the war artist Vasily Vereshchagin.
