Andau (Hungarian: Mosontarcsa, Moson-Tarcsa) is a village in Burgenland, Austria, near the border of Hungary. It is situated in the flat, lake-studded Seewinkel region which is part of the Little Hungarian Plain.
During the Hungarian revolution of 1956, 70,000 refugees escaped the communist regime by crossing the border from Hungary into Austria over a small wooden bridge, called the Brücke von Andau. This was memorialized by James A. Michener in his book The Bridge at Andau.
