Srednekolymsk Airport (IATA: SEK, ICAO: UESK) is a small regional airport serving the town of Srednekolymsk in the Sakha Republic (Yakutia), Russia. Located in a remote area of northeastern Siberia, the airport plays a critical role in connecting an isolated community accessible only by air for much of the year due to the extreme subarctic climate and lack of permanent road connections. The airport operates primarily domestic routes, linking Srednekolymsk to larger regional hubs such as Yakutsk. Air transport is essentially a lifeline for the local population, supporting the delivery of goods, medical services, and passenger travel during long winter months when river and overland routes are impassable.
