Artillery Quartermaster Grigory Mykytovych Vakulenchuk (Russian: Григо́рий Ники́тич Вакуленчу́к, 1877– 14/27 June 1905) was a Ukrainian sailor in the Imperial Russian Navy. He was born in Velyki Korovyntsi (now in Zhytomyr Oblast). He served on the Russian battleship Potemkin. After the crew discovered their meat was maggot-ridden, Vakulenchuk called for a boycott rather than a full uprising. His death and funeral are important incidents in Sergei Eisenstein's film Battleship Potemkin, where he was played by Aleksandr Antonov.
