Theodefrid (Latin: Theodefridus) was the Frankish duke of the Alemanni in the Diocese of Avenches until 573, when Marius became bishop and took over the secular affairs of the diocese. Marius in his Chronicon mentioned five dukes that ruled Avenches between 548 and 573. Theodefrid was the last and a successor of Vaefar. Marius calls him a Frank, but Agathias has led some to believe he was an Aleman.
