The Church of St. Mary of the Perpetual Assistance located in Tarnopol, Eastern Galicia (now Ternopil, Ukraine), was a church located in the city's centre which functioned as the parochial church of Ternopil's Roman Catholic community. The church was built by the Latin Deacon of Ternopil and local rector, prelate Bolesław Twardowski in the years 1903-1908 as a parish church for the city. The design of the neo-gothic church was made by Teodor Talowski. It was one of his alternative projects for the Church of St. Elizabeth in Lviv.
