Milwaukee Airport also known as General Mitchell International Airport (IATA: MKE, ICAO: KMKE, FAA LID: MKE) is a county-owned, joint civil-military, public airport located five miles (8 km) south of the central business district of Milwaukee, Wisconsin.

The Milwaukee Airport is named after United States Army Air Service General Billy Mitchell, who was raised in Milwaukee and is often regarded as the father of the United States Air Force. Along with being the primary airport for Milwaukee, Mitchell International has sometimes been described as Chicago’s third airport, as many travelers in the suburbs north of Chicago use it as an alternative to Chicago O’Hare and Chicago Midway. It is also used by travelers throughout Wisconsin and Northern Illinois. An Amtrak railway station opened at the airport in 2005; the station is served by Amtrak’s Hiawatha Service line running between Chicago and Milwaukee several times daily.

The Milwaukee Airport’s weather station is used as the official point for Milwaukee weather observations and records by the National Weather Service, whose area office is located in Sullivan.
