Kvarkeno Airport (ICAO: UWOH) is a small general aviation and regional airfield located in Kvarkeno, a rural settlement in the Orenburg Oblast of Russia. The airport serves the local administrative district and surrounding areas, operating at a limited capacity typical of remote Russian regional airfields. Due to its small size and remote location, the airport sees minimal scheduled commercial traffic and is primarily used for light aircraft, emergency, and utility flights. Detailed operational data on the facility is scarce in publicly available sources.
