Flying Leatherneck Aviation Museum, Aviation museum in Irvine, United States

The Flying Leatherneck Aviation Museum is a United States Marine Corps aviation museum now housed in Hangar 297 at the Orange County Great Park in Irvine, California. Its outdoor exhibits display 31 historical aircraft along with military vehicles and equipment, while indoor galleries hold photographs, artifacts and artwork from the early days of aviation to the present.

The El Toro Historical Center and Command Museum opened in June 1991 in a squadron aviation building at Marine Corps Air Station El Toro, and by 1998 it was renamed the Jay W. Hubbard Command Museum. When MCAS El Toro closed in 1999, it became the Flying Leatherneck Aviation Museum and its 41 aircraft were towed by trailer to Naval Air Station Miramar, where it reopened on 25 May 2000. Collections moved to Hangar 297 at the Orange County Great Park in Irvine by December 2024, and ground was broken on a 131,000 sq ft facility on 28 October 2025.

The Flying Leatherneck Historical Foundation runs the museum's interpretive programs, including school field trips, STEM education, the Marine Spouse Award, and annual student essay and art contests. Indoor exhibits hold photographs, artifacts and artwork from the early days of aviation to the present.

The museum is now located at the Great Park in Irvine and is most easily reached by car, with parking available on site. Some of the aircraft are displayed outdoors, so on warm days it is worth bringing sun protection when walking the grounds.

One aircraft in the collection actually carried the American ambassador during the 1975 evacuation from Vietnam and can still be seen on display today. That single plane connects visitors to one of the most widely remembered moments in 20th-century American foreign policy.
