Grand Forks International Airport (IATA: GFK, ICAO: KGFK, FAA LID: GFK) is a public airport five miles (8 km) northwest of Grand Forks, in Grand Forks County, North Dakota, United States. GFK has no scheduled passenger flights out of the country but has an "international" title (like many other airports) because it has customs service for arrivals from Canada and other countries.

The airport, sometimes called Mark Andrews International Airport after Mark Andrews, a former U.S. House Representative and U.S. Senator from North Dakota, is owned by the Grand Forks Regional Airport Authority and located on U.S. Highway 2, around four miles (6 km) west of Interstate 29, within city limits in a detached section of the city that is surrounded by Rye Township.

In 2009 the airport's FAA control tower was the 23rd-busiest in the nation, with 346,165 tower operations. About 90% of all operations at GFK are flights operated by the University of North Dakota's John D. Odegard School of Aerospace Sciences, which is based on the field.

It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a non-hub primary commercial service facility.
