Gabriel Yurij Vynnyckyj (Ukrainian: Юрій Винницький, Belarusian: Юры Віньніцкі, Polish: Jerzy Winnicki) (1660—1713) was the Administrator of Kiev–Galicia from 1708 and the "Metropolitan of Kiev, Galicia and all Ruthenia"[a] of the Ukrainian Greek Catholic Church from 1710 to his death in 1713.

Gabriel was still a layman, thus on 20 April 1700 he entered in the Order of Saint Basil the Great taking the religious name of Yurij (George), and shortly later was ordained as a priest.

[6] In 1707, after the death of bishop Joseph De Camillis, he was appointed administrator of the Eparchy of Mukacheve for which there were political problems for the succession.

He was shortly later elected Metropolitan of Kiev and Galicia, but because of the ongoing Great Northern War, he could be formally confirmed by the king only until 1710.

Vynnyckyj was the leader of the Ukrainian Greek Catholic Church in a very difficult period, during the Great Northern War (1700-1721), and under the armed opposition of Peter I of Russia to the Greek Catholic Church, particularly in the eparchy of Lutzk.
