The Lübeck–Bad Kleinen railway is a single-track, non-electrified main line between the German states of Schleswig-Holstein and Mecklenburg-Vorpommern. Its construction was started by the Lübeck-Kleinen Railway Company (German: Lübeck-Kleinener Eisenbahn-Gesellschaft) and, after that company's bankruptcy, it was completed and opened by the Friedrich-Franz Railway (Friedrich-Franz-Eisenbahn).
