Leinfelden-Echterdingen is a town in the district of Esslingen, in Baden-Württemberg, Germany. It is located approximately 10 km south of Stuttgart, near the Stuttgart Airport and directly adjacent to the newly built Stuttgart Trade Fair. The town was formed on 1 January 1975 by the merging of four former municipalities: Leinfelden, Echterdingen, Musberg and Stetten auf den Fildern. Zeppelin LZ 4 caught fire and burned out in Echterdingen in August 1908.
