Artillery Quartermaster Grigory Meketovich Vakulinchuk (1877– 14/27 June 1905) was a Ukrainian sailor in the Russian Navy. He was born in Velki Koroventsi (now in Zhytomyr Oblast). He served on the Russian battleship Potemkin. After the crew discovered their meat was maggot-ridden, Vakulinchuk 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.
