Werdo (born before 778; died 30 March 812) was abbot of the Abbey of Saint Gall in St. Gallen.
The diocesan priest Werdo was first mentioned in records in 778.[1] After the resignation of Waldo von Reichenau in 784, he was named abbot of the Abbey of Saint Gall by the bishop Egino von Konstanz (from the bishopric of Constance). He is presumed to have died on 30 March 812.
