Vasily Stepanovich Zavoyko (; 1809-1898) was an admiral in the Russian navy. Born to a noble Ukrainian family of Poltava Governorate, in 1827 he took part in the Battle of Navarino, and in 1835-1838 he twice circumnavigated the Earth. In 1854, during the Crimean War, Zavoyko led the successful defence against the Siege of Petropavlovsk by the allied British-French troops commanded by Rear Admirals David Price and Auguste Febvrier Despointes. Zavoyko managed to repel the superior allied forces and even captured the British banner.
