Tedald (died 1012), of the House of Canossa, was the count of Brescia from 980, Modena, Ferrara, and Reggio from 981, and Mantua from 1006. He used the title of margrave because of his vast comital holdings and their frontier nature. His family's seat was Canossa and he was the son of Adalbert Azzo of Canossa who had supported Otto I against Berengar of Ivrea and Adalbert of Ivrea. His rise was largely due to his loyalty to the Ottonian Dynasty. Tedald married Willa daughter of Hubert of Spoleto, natural son of Hugh of Italy.
