Douthitt Strip (FAA LID: 23CN) is a privately owned, private use airport located one nautical mile (2 km) east of the central business district of El Centro, a city in Imperial County, California, United States.

It provided contract glider training to the United States Army Air Forces from 1942 to 1944. Training was provided by Aeronautical Training Center, Inc. It used primarily C-47 Skytrains and Waco CG-4 unpowered gliders. The mission of the school was to train glider pilot students in proficiency in operation of gliders in various types of towed and soaring flight, both day and night, and in servicing gliders in the field.

Douthitt Strip has two runways with dirt surfaces: 4/22 is 1,800 by 100 feet (549 x 30 m) and 8/26 is 1,400 by 100 feet (427 x 30 m). There are 23 aircraft based at this airport: 91% single-engine and 9% ultralight.
