Church of the Ascension (Ukrainian: Церква Вознесіння Господнього) is a Greek Catholic Parish Church (UGCC) in Chortkiv of the Chortkiv urban hromada of the Chortkiv Raion of the Ternopil Oblast, and an architectural monument of national importance.

The parish was founded in 1717. The church was built in 1630. During the attack on Chortkiv by Turks and Tatars in 1640 and 1672, the church was horribly destroyed. The church was finally rebuilt in 1717. Until then, it had the title of St. Nicholas. Worship services were resumed in June 1717. The parish became Greek Catholic.

The construction of the Church of the Ascension was carried out with the direct participation and at the expense of the residents of Dolishnia Vyhnanka, as well as with the assistance of the church fraternity of Chortkiv and craftsmen.

From the beginning to the middle of the XX century. The Church of the Ascension did not function, it was in an abandoned state. In July 1967, the architect V. Zakharov developed a project for the restoration of the church, after which the Church of the Ascension was transferred to state protection as a monument of wooden architecture of Ukraine in the XVIII century.

After 1946, the Greek Catholics of the former parish continued to worship underground. The first service after the resumption of activities took place in a suburban cemetery in Siniakovo, where a chapel was installed for Easter 1989.
