The Mid-America Air Museum is an aerospace and aircraft museum located at the Liberal Mid-America Regional Airport in Liberal, Kansas, United States.

The Mid-America Air Museum is the largest aircraft museum in Kansas. It has on display over 100 aircraft (both within the museum's primary building and on the adjacent tarmac), a gift store, and several displays of photographs and ephemera relating to the history of aviation in the region.

The museum is on Liberal Mid-America Regional Airport, originally known as Liberal Army Air Field that served as a B-24 Liberator training base during the Second World War.

The museum is located within a hangar that formerly belonged to Beech Aircraft, where Beech produced Beech Musketeer, Beechcraft Baron, and Beechcraft Duchess light airplanes, in the 1960s and 1970s.

The museum started with the donation, by the late Colonel Tom Thomas, Jr., of his personal collection: over 50 aircraft (valued at over $3 million) to the City of Liberal.

It originally opened as the Mid America Air Group Flying Museum in 1984 in Ada, Oklahoma with 38 planes.
