Ternopil is a city in western Ukraine, located on the banks of the Seret River. Until 1944, it was known mostly as Tarnopol. Ternopil is one of the major cities of Western Ukraine and the historical regions of Galicia and Podolia. It is served by Ternopil Airport. In January 2019, the population of Ternopil was estimated at 221,820.

The city is the administrative center of Ternopil Oblast (region), as well as of the surrounding Ternopil Raion (district) within the oblast. However, Ternopil is a city of regional significance, thus being subject directly to the oblast authorities rather than to the raion administration which is housed in the city as well.
