Klesiv (uk|Клесів; pl|Klesów) is a rural settlement in Sarny Raion (district) of Rivne Oblast (province) in western Ukraine. Population:
Klesiv was first founded in the beginning of the 20th century. It was a settlement in Volhynia Governorate of the Russian Empire.
In the Second Polish Republic Klesów was part of Volhynian Voivodeship. After the Soviet annexation of Western Ukraine, Klesiv acquired the status of an urban-type settlement in 1940.
Since July 1941 until January 1944 it was occupied by Axis troops.
In January 1989 the population was 5107 people.[2]
In 2013 the population was 4639 people.[3]
On 26 January 2024, a new law entered into force which abolished the status of urban-type settlement, and Klesiv became a rural settlement.[4]
There are placer deposits of Rovno amber from the Oligocene Mezhigorje Formation near Klesiv.[5]
