Plectrude was a Frankish aristocrat who served as the wife of Pepin of Herstal. Born in Austrasia around 650, she was highly influential during her husband's reign, often appearing as a joint signatory on his legal documents. Following the death of Pepin in 714, she acted as the regent for her grandson, Theudoald. Her political efforts to maintain her grandson's inheritance led to significant conflict with Charles Martel, ultimately resulting in her loss of power and her death in Cologne around 717 or 718.
