Russian frigate General Admiral
''General Admiral'' ((ロシア語:Генерал-адмирал)) was a screw frigate ordered by the Imperial Russian Navy from the United States before the American Civil War. She spent the bulk of her career in the Mediterranean Sea where she evacuated insurgents and their families from Crete in 1868 during the Cretan Revolt. She was struck from the Navy List the following year and broken up in 1870.

The upper deck had twenty-four 60-pounder guns and two long 36-pounder chase guns. Two 3-pood shell guns were mounted fore and aft on revolving platforms.〔 In 1862 her armament was revised and two 60-pounder and the two long 36-pounder guns on her upper deck were removed.
