Rivne (Ukrainian: Рівне) or Rovno (Polish: Równe; Russian: Ровно; Yiddish: ראָוונע) is a historic city in western Ukraine. It is the administrative center of the Rivne Oblast (province), as well as the administrative center of the surrounding Rivne Raion (district) within the oblast.

Rivne is an important transportation hub, with the international Rivne Airport, and rail links to Zdolbuniv, Sarny and Kovel, as well as highways linking it with Brest, Kiev and Lviv.

The estimated population was around 247,750 as of 2010.

Rivne was first mentioned in 1283 as one of the inhabited places of Halych-Volhynia. From the second half of the 14th century it was under the Great Duchy of Lithuania and from 1569 in the Polish-Lithuanian Commonwealth. In 1492 the city was granted Magdeburg rights. Following the partition of Poland, in 1793 Rivne became a part of Russian Empire, and in 1797 it was declared as a regional town of the Volhynian Governorate.

During World War I and the period of chaos shortly after, it was briefly under German, Ukrainian, Bolshevik, and Polish forces. In April–May 1919 Rivne served as the temporary capital of Ukrainian People's Republic. At the conclusion of the conflict, in accordance with the Riga Peace Treaty of 1921 it became a part of Polish Volhynian Voivodeship for the period between the two World Wars.
