Hryhoriy Hulyanytsky (Ukrainian: Григорій Гуляницький) (died 1679) was a Ukrainian Cossack colonel, a skilled warrior and a shrewd politician. Hryhoriy Hulyanytsky was born to a family of Ruthenian gentry of Ostoja Coat of Arms in the town of Korsun. His date of birth and earlier period of life are unknown. During the Khmelnytsky Uprising of 1648–54, Hulyanytsky was sent by hetman Bohdan Khmelnytsky as an envoy to Muscovy. Hulyanytsky went to Moscow on two occasions, in 1649 and in 1654, to help negotiate the terms of the Treaty of Pereyaslav.
