The Russian battleship Poltava was one of three Petropavlovsk-class pre-dreadnought battleships built for the Imperial Russian Navy in the 1890s. The ship was transferred to the Pacific Squadron shortly after completion and based at Port Arthur from 1901. During the Russo-Japanese War of 1904–1905, she participated in the Battle of Port Arthur and was heavily damaged during the Battle of the Yellow Sea. She was sunk by Japanese artillery during the subsequent siege of Port Arthur in December 1904, but was raised by the Imperial Japanese Navy (IJN) after the war and renamed Tango (丹後).

The Petropavlovsk class, sometimes referred to as the Poltava class, was a group of three pre-dreadnought battleships built for the Imperial Russian Navy during the 1890s. They were transferred to the Pacific Squadron shortly after their completion in 1899–1900 and were based at Port Arthur before the start of the Russo-Japanese War of 1904–1905. All three ships participated in the Battle of Port Arthur on the second day of the war. Petropavlovsk sank two months after the war began after striking one or more mines laid by the Japanese. Her two sister ships, Sevastopol and Poltava, took part in the Battle of the Yellow Sea in August 1904 and were sunk or scuttled during the final stages of the siege of Port Arthur in early 1905.
