Ozark Air Lines operated in the United States from 1950 until 1986 when it was purchased by Trans World Airlines. A smaller airline with the same name (whose operating certificate was purchased by Great Plains Airlines) operated in 2000–2001. From 1950 until 1986 Ozark's headquarters was at Lambert–St. Louis International Airport in St. Louis County, Missouri.

On 1 September 1943 Ozark Air Lines was founded to fly services from Springfield, Missouri, and in January 1945 it began flights between Springfield and St. Louis on Beech 17 Staggerwings, replaced by Cessna AT-17 Bobcat in the late 1940s. The required license from the Civil Aeronautics Board was not forthcoming and operations had to stop.

In July 1950 Ozark was granted a certificate to operate Parks Air Transport routes not previously activated. Services were started on 26 September 1950 using Douglas DC-3s from St. Louis to Chicago, Tulsa and Memphis. In 1955 the airline had 13 DC-3s flying to 35 cities between Sioux City, Indianapolis, Wichita and Nashville. Ozark's main hub was Lambert–St. Louis International Airport. Like other Local Service airlines it was subsidized; in 1962 its operating "revenues" of $14.0 million included $4.5 million of federal subsidy.

In 1960 the fleet added turboprop Fairchild F-27s; Martin 4-0-4s were added in 1964.
