Ogilvie River Airport (ICAO: CFS4) is a small, remote airstrip located in the Ogilvie River area of Yukon, Canada. It serves as a bush airstrip supporting access to the wilderness regions of central Yukon, where road access is extremely limited or nonexistent. The airport is a basic facility with no scheduled commercial airline service, functioning primarily as a landing area for bush planes, charter flights, and emergency operations. It is typical of the many remote northern Canadian airstrips that provide essential lifeline connections to isolated communities and resource operations.
