May River Airstrip (IATA: MRH, ICAO: AYRV) is a small, remote airstrip located near the May River in the East Sepik Province of Papua New Guinea. It serves as a vital lifeline for isolated communities in the surrounding jungle region, where air transport is the primary means of access. The airstrip supports missionary aviation, charter services, and essential supply flights for villages along the May River. Like many remote PNG airstrips, it has a grass or compacted-earth runway suitable only for small propeller-driven aircraft. Ground infrastructure at the site is minimal, with no formal terminal building or commercial facilities. Access to the broader region depends almost entirely on flight connections to larger centers such as Wewak.
