The Otto-Lilienthal-Museum in Anklam ( Germany) is a museum about the "glider king" Otto Lilienthal, the flight pioneer, as well as a pioneer in technical, social and cultural projects.

The town of Anklam is Lilienthal’s birth place. Various objects belonging to the life and work of Otto Lilienthal, among them a reconstruction of a glider from the year 1925 have been part of a local history museum, founded in 1927. The Otto-Lilienthal-Museum was opened in 1991 as a biographical technical museum. Today the museum houses the largest collection of Lilienthal aircraft in reconstruction.

The museum archives contain everything that is known about the first successful glider pilot, essays, documents, including a photo archive, replica and models of all known gliders and aircraft of Lilienthal. Moreover, the brothers Otto and Gustav Lilienthal were very prolific inventors of steam engines, toys, as well as initiators of numerous social and cultural projects. The museum acquired a large collection of hang gliders and shows models of aircraft, from the time before the first successful flights, represent the early history of aviation and the prehistory of the aircraft.

In 1996 the museum has been awarded the title "FAI Recognized Museum" from the International Organisation of Aeronautics FAI, and in 1999 the museum was the first one in the former East-Germany area which was awarded the "European Museum of the Year Award - Special Commendation" by the European Museum Forum. The state minister for culture and media of the Fed. Rep. of Germany awarded the museum the title "German National Memorial" since 2001.
