Olevsk (Ukrainian: Олевськ, IPA: [oˈlɛu̯sʲk] ⓘ; Polish: Olewsk; Yiddish: אלעווסק) is a city in Korosten Raion, Zhytomyr Oblast, Ukraine.

In 1641 Olevsk was granted Magdeburg city rights by Polish King Władysław IV Vasa.

During World War II on November 15 or 21, 1941, members of Taras Bulba-Borovets' Ukrainian People's Revolutionary Army collaborated with the German administration in taking more than 500 Jews from Olevsk to Varvarivka, where they were murdered.

[2] On December 25, 2011, the city council of Olevsk renamed the streets of the city that bore the names of Soviet leaders, naming them in honor of prominent figures of the Ukrainian nationalist and patriotic movement.

Instead, they were named after Olena Teliha, Oleh Olzhych, Hetman Vyhovsky, Oleksiy Opanasiuk, Heroes of Kruty, the 20th anniversary of Ukraine's independence, and Yuriy Tiutiunnyk.
