Kirensk (Russian: Киренск, IPA: [ˈkʲirʲɪnsk]) is a town and the administrative center of Kirensky District in Irkutsk Oblast, Russia, located at the confluence of the Kirenga and Lena Rivers, 950 kilometers (590 mi) north of Irkutsk,[2] the administrative center of the oblast.

[citation needed] In the 19th century, a large number of political prisoners were forcibly resettled here, among whom was Józef Piłsudski.

In the 1970s, a dam was built across one mouth of the Kirenga (the place was originally an island) to reduce flooding and ice jams.

[5] There is ship transport along the Lena in summer and an airport, but no railroad, and no proper road link to the rest of Russia.

During World War II, it was a staging point for American aircraft transferred to Russia via Alaska.
