General Mitchell International Airport (IATA: MKE, ICAO: KMKE) is an airport located in Milwaukee, Wisconsin, US. It is named after United States Army Air Service General Billy Mitchell, who was raised in Milwaukee and often regarded as the father of the United States Air Force. The airport is the main hub of Midwest Airlines.

Mitchell International has sometimes been described as Chicago's third airport, as many Chicago travellers seek to avoid O'Hare International Airport or Midway Airport. It is also used by travellers throughout Wisconsin and Northern Illinois as an alternative to other local airports. Mitchell is primarily thought of as a regional airport, as few international carriers serve it; but it does have direct service to Toronto via Air Canada Jazz and Midwest Connect. It also offers charter service to some non-domestic destinations. An Amtrak railway station opened at the airport in 2005, which provides daily round trip service to and from Chicago.
