The LFG V 20 Arkona (named for Kap Arkona on Rügen) was a seaplane airliner produced in small quantities in Germany in the early 1920s. It was a conventional, strut-braced, low-wing monoplane with an enclosed cabin for four passengers. The undercarriage consisted of twin pontoons. Originally produced in wood, a metal version of the aircraft was also developed
The V 20s were operated by Luft-Fahrzeug on its Hamburg-Stettin-Danzig and Stettin-Swinemünde-Stralsund routes.
