Mainz-Finthen Airfield (ICAO: EDFZ) is a general aviation airport located in the Finthen district of Mainz, Rhineland-Palatinate, Germany. It serves private pilots, flight training, and light aircraft operations rather than scheduled commercial airline service. The airfield is home to several flying clubs and flight schools, making it an important facility for recreational and training aviation in the Rhine-Main area. It operates as a controlled airfield and handles a variety of small aircraft movements throughout the year. Due to its proximity to Frankfurt Airport and other regional airports, Mainz-Finthen does not handle commercial passenger traffic but plays a meaningful role in supporting general aviation in the wider Frankfurt Rhine-Main metropolitan region.
