Josaphat Bulhak (20 April 1758 – 25 February 1838) was a hierarch of the Ruthenian Uniate Church in the western Russian empire.

In 1795, after the Second Partition of Poland, he was removed from his seat and the Turov bishopric was closed by the Russian government.

In 1817, he was appointed to the Metropolitan seat of Kyiv by Tsar Alexander I, thus becoming a titular head of the Uniate church in the Russian empire.

In 1818, he also served as the head of the Uniate department of the Roman Catholic Spiritual College and also Vice President of the Russian Biblical Fellowship.

In the last 10 years of his life, he was surrounded by hierarchs hostile to the independence of the Uniate church, such as Bishop Yosyf Semashko.
