Uglegorsk (Russian: Углего́рск) is a coastal port town and the administrative center of Uglegorsky District in Sakhalin Oblast, Russia, located on the west coast of Sakhalin Island, 277 kilometers (172 mi) northwest of Yuzhno-Sakhalinsk, the administrative center of the oblast.

[9] It was founded as Esutoru (恵須取), meaning "between capes" in the Ainu language, during Japanese rule in 1905.

[citation needed] It came to Soviet control along with the rest of the Sakhalin Island with the defeat of Japan in World War II.

For a time, Uglegorsk was put under consideration for potential sites for the new capital of Sakhalin Oblast.

The weather on the western side of Sakhalin tends to be drier and more settled than on the eastern side, since the winds from the combined force of the Siberian High and Aleutian Low run almost parallel to the coast with very little travel over water.
