The Buchach Monastery of the Exaltation of the Holy Cross of Basilian Fathers (Ukrainian: Бучацький монастир отців Василіян Воздвиження Чесного Хреста Господнього) is a Basilian monastery in Buchach, Ternopil Oblast, Ukraine.

For centuries, it has been one of the centers of the Ukrainian Greek Catholic Church in Western Ukraine.

It was founded by Stefan Aleksander Potocki and his wife Joanna née Sieniawska, daughter of Mikołaj Hieronim Sieniawski.

In the charter (signed on 7 December 1712 in Lublin) they donated 30,000 zlotys to the Basilians with the purpose of improving education of the Greek Catholic clergy.

In 1714 the Archdiocese of Lviv (in the person of Archbishop Jan Skarbek) transferred a small Latin Catholic church in Buchach to the local Basilians.
