The Loening OL was an American two-seat amphibious biplane built by Loening for the United States Army Air Corps and the United States Navy.

First flown in 1923, the OL was a high-performance amphibian with a large single float and stabilising floats fitted underneath each lower wing. It had retractable landing gear and a tailskid for operations on land. It had a tandem open cockpit for a crew of two.

The United States Army Air Corps ordered four prototypes as the XCOA-1 powered by a 400hp Liberty V-1650-1 engine. A number of variants were introduced for both the Army and United States Navy. During later production the company merged with the Keystone Aircraft Corporation.
