Huntsville International Airport (IATA: HSV, ICAO: KHSV, FAA LID: HSV) (Carl T. Jones Field) is a public airport and spaceport ten miles southwest of downtown Huntsville, in Madison County, Alabama, United States. The FAA has designated the Huntsville International Airport as a Re-entry site for the Dream Chaser, a spaceplane operated by Sierra Space to make reentries from Low Earth Orbit (LEO).

The airport is part of the Port of Huntsville (along with the International Intermodal Center and Jetplex Industrial Park), and serves the Huntsville-Decatur Combined Statistical Area. Opened in October 1967 as the Huntsville Jetport, it was the third airport for Huntsville. The airport has 12 gates with restrooms, shops, restaurants, phones and murals depicting aviation and space exploration scenes. The airport also has on a 3-star hotel on the premises. The Four Points by Sheraton is located above the ticketing area and lobby, (adjacent to the terminal is a parking garage and to opposite sides are the control tower and a golf course).

The airport's west runway, at 12,600 ft (3,800 m), is the second longest commercial runway in the southeastern United States, being 400 ft (120 m) shorter than the longest runway at Miami International Airport. Huntsville is frequently used as a diversion airport from larger hubs in the Southeast, such as Atlanta, due to its long runways and sophisticated snow removal and de-icing equipment.

The airport's "Fly Huntsville" marketing campaign encourages passengers to depart from Huntsville instead of driving to Birmingham or Nashville.
