Town and the administrative center of Okhinsky District of Sakhalin Oblast, Russia. Population: 23,008 (2010 Census). Okha is located on the east coast of the far north of Sakhalin island, just south of the isthmus of the Schmidt Peninsula, approximately 850 km (530 mi) north of Yuzhno-Sakhalinsk, near the shoreline of the Sea of Okhotsk.
It was founded shortly after the discovery of petroleum in the area in 1880, initially under the name Okhe. The name is derived from an Ainu word meaning Bad Water. Industrial exploitation of the petroleum reserves began in 1923, during the Japanese occupation of Sakhalin from 1920 to 1925. During this time the town was called Okutan (奥端町, Okutan-chō) or Okuhan (奥哈町, Okuhan-chō) depending on Kanji used. Town status was granted to it in 1938.
