Sanostee Airport (ICAO: NM27) is a small, uncontrolled general aviation facility located in the Sanostee community on the Navajo Nation in northwestern New Mexico, United States. Despite its nominal association with Gallup in some databases, the airstrip is geographically situated closer to the Sanostee area near the Four Corners region. The airport serves primarily as a local utility airstrip for private and general aviation traffic, supporting access to the remote, rural communities of the Navajo Nation. It is not served by commercial airlines and has no scheduled passenger services.
