General Dewitt Spain Airport (ICAO: KM01) is a public general aviation airport located in Memphis, Tennessee, situated near the banks of the Mississippi River in the northern part of the city. It serves as a reliever airport to Memphis International Airport, accommodating small private aircraft, charter flights, and light aviation activity. The airport is named in honor of General Dewitt Spain, a prominent Memphis civic leader and aviation advocate. It is owned and operated by the City of Memphis and managed as part of the Memphis-Shelby County Airport Authority system. The facility features a single runway and supports fixed-base operators (FBOs) serving the general aviation community. Due to its proximity to downtown Memphis and the river, the airport occupies a relatively compact footprint and does not handle scheduled commercial airline service. It plays an important role in supporting business aviation and flight training operations in the greater Memphis metropolitan area.
