The Beriev Be-103 Bekas (English: Snipe) is an amphibious seaplane designed by the Beriev Aircraft Company and constructed by the Komsomolsk-on-Amur Aircraft Production Association (KnAAPO) in Russia. Intended for autonomous operation in the unmarked areas of Russia's far north and Siberia, the Be-103 was designed for short-haul routes in regions that have rivers, lakes and streams, but are otherwise inaccessible.

The Be-103 is a mid-wing monoplane, making use of the modified wing roots as water-displacing sponsons. It features an all-moving slab tail and retractable tricycle landing gear for land operations. Its hallmark and most distinguishing design feature is the water-displacing wing, an unusual feature for a seaplane, with three aquaplaning implements (planing step, port and starboard wing trailing edges) which substantially enhance the aircraft's on-the-water stability and seaworthiness.

The Be-103 features include an advanced, blended wing, swept at 22°, with 11-foot (3.4 m)-long fixed leading edge slats, trailing-link main landing gear, and three-bladed MT-12 reverse pitch propellers. Fuel is stored in the wet wings. The aircraft is built from aluminum-lithium alloy with titanium used in high-stress areas. A 30-parameter, five-hour flight data recorder, engine fire-detection systems and an ice detector are also standard, as are hydraulic brakes. However, unlike most modern aircraft, the Be-103 is not equipped with wing flaps.
