Dolyna (Ukrainian: Долина, IPA: [doˈlɪnɐ] ⓘ; Polish: Dolina; Yiddish: דאלינע) is a city in Kalush Raion, Ivano-Frankivsk Oblast, south-western Ukraine.

In the Second Polish Republic, the town, with population of almost 10,000, belonged to the Stanisławów Voivodeship and was the capital of the Dolina County.

During World War II the city was occupied by the USSR (September 1939 - June 1941), Hungary (July 1941), and Germany (August 1941 – 1944).

Dolyna is the only city in Ukraine to have received the European Energy Efficiency Management Certificate.

For more than 10 years, Dolyna has insulated all public sector institutions in the city, modernized street lighting, abandoned centralized heating, and converted more than 60% of large boiler houses to alternative fuels, which is the highest rate in Ukraine.

The main priorities of the city are the development of tourism potential, as well as the restoration and preservation of an architectural monument of national importance - the buildings of the former saltworks of the late XIX century in the old part of Dolyna.
