Yankuntza Airstrip (ICAO: SEYK) is a small, unscheduled airstrip located in the Yankuntza area of Zamora-Chinchipe Province in southeastern Ecuador, deep within the Amazon basin region. It primarily serves indigenous Shuar communities and supports light general aviation traffic, including missionary, humanitarian, and occasionally government flights. The airstrip is unpaved and suitable only for small single-engine or light twin-engine aircraft, given the challenging terrain and limited infrastructure. It plays an important logistical role in connecting remote jungle communities that lack road access to larger population centers. No commercial airline services operate from this facility. It functions as a fundamental link for remote community access, medical evacuations, and supply deliveries in an otherwise difficult-to-reach part of Ecuador's Amazon frontier.
