Anadyr is a port town and the administrative center of Chukotka Autonomous Okrug, Russia, located at the mouth of the Anadyr River, on the tip of the southern promontory that protrudes into Anadyrsky Liman. Anadyr is the most eastern town in Russia (more easterly locations, such as Provideniya and Uelen, do not have town status). Population: 13,045 (2010). Although the town itself has only been in existence for just over a century, the origins of the name Anadyr are much older. The name initially derives from the Yukaghir word "any-an" meaning "river". When Semyon Dezhnev met Yukaghir peoples in the area and the indigenous name was corrupted to form "Onandyr", later Anadyrsk, the name of the ostrog (fort) upstream of the present-day settlement, from which the current name is derived. The ostrog was the only Russian settlement east of the Kolyma River on the Chukotka Peninsula for most of the 18th century, though this original settlement was situated further up the Anadyr River, nearer to Markovo than the site of the current town.
