Fastrada (765-794) was an East Frankish noblewoman. She became the third wife of Charlemagne, marrying him in 784. She bore him two children:
She died during the synod of Frankfurt and had been buried in St. Alban's Abbey, Mainz, long before the abbey was finalized. Due to archbishop Richulfs influence, Fastrada was not buried in the Basilique Saint-Denis, the burial site of almost all the Frankish and French monarchs, nor St. Arnulf's Abbey near Metz. After the destruction of St. Alban's Abbey in 1552, her tombstone had been transferred to Mainz Cathedral, where it can be seen today in the wall of the southern nave.
