Hoosier Air Museum was an aviation museum at DeKalb County Airport in Auburn, Indiana, created by the Hoosier Warbirds, a group of enthusiasts who began meeting in 1991. After raising funds for a hangar that opened in 2000, the museum broadened its holdings with aircraft, engines, vehicles, and exhibits from other collections. Its facilities grew to include a large hangar, an event hall, and a library, while its displays covered major themes in American aviation and airpower history, including the Tuskegee Airmen, the Women Airforce Service Pilots, the Flying Tigers, and World War Two. It closed in 2019 because of too few volunteers and limited site access, and much of the collection was transferred elsewhere.
