Elizabeth was a daughter of Duke Frederick "the Wise" of Bavaria-Landshut and his second wife Maddalena Visconti.

On 18 September 1401 she married Frederick VI of Hohenzollern, Burgrave of Nuremberg, who was promoted to Elector of Brandenburg in 1415 and ruled as "Elector Frederick I".

During her husband's long journeys to Italy, Hungary, and to the Council of Constance, she represented him wisely despite the great political problems Brandenburg was experiencing at the time.
