Mid-America Air Museum, Aviation museum in Liberal, Kansas, United States.

The Mid-America Air Museum displays more than one hundred aircraft in a large exhibition space, ranging from military jets and helicopters to vintage propeller-driven planes. The collection covers different eras and types of aircraft arranged for visitors to view and study.

The museum opened in 1984 as the Mid America Air Group Flying Museum in Ada, Oklahoma, with 38 planes. It moved to Liberal, Kansas, after Colonel Tom Thomas, Jr. donated his collection of over 50 aircraft, valued at over $3 million, to the city. It now occupies a hangar where Beech Aircraft built Musketeer, Baron and Duchess light airplanes in the 1960s and 1970s, on the former Liberal Army Air Field, a B-24 Liberator training base in the Second World War.

The museum opened as the Mid America Air Group Flying Museum in Ada, Oklahoma, in 1984 with 38 planes, before moving to Liberal. Its collection grew through transfers from the Cosmosphere in Hutchinson, the Combat Air Museum in Topeka and the Kansas Aviation Museum in Wichita. Strings of small American flags hang from the ceiling above the aircraft.

The museum has parking available on site, and the aircraft are displayed across several connected buildings that are easy to navigate. Comfortable walking shoes are recommended since the grounds are spacious and require time to explore thoroughly.
