New York's Orange County Airport (IATA: MGJ, ICAO: KMGJ, FAA LID: MGJ) is an untowered airport located one nautical mile (2 km) southwest of the village of Montgomery, in the Town of Montgomery, United States, at the junction of state highways 211 and 416. It is owned and operated by Orange County. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a general aviation facility.

It is a popular place for aspiring local pilots to learn to fly or practice their skills. With 125,000 takeoffs and landings annually, it was New York's second-busiest general-aviation airport in 2006.

Transmissions between pilots and the airport are rebroadcast on a one-watt station at 88.1 megahertz, so it is possible to tune into them on a standard car radio while driving in the vicinity.

The airport's low traffic and out-of-the-way location have made it a popular place to store private jets. In 2006 county officials were reported to be working on a deal with a local developer to build 10 private luxury hangars to cater to what they saw as a growing market and raise money for the airport without raising taxes.
