Mephisto is a World War I German tank, the only surviving example of an A7V. In April 1918, during a German attack at Villers-Bretonneux on the Western Front, it became stuck in a shell-hole and was abandoned by its crew. It was recovered by Allied troops about three months later and, after the war, taken to Australia as a trophy. Mephisto is housed at the Queensland Museum, in Brisbane, in the Anzac Legacy Gallery. It is not in running order.
