Poppa of Bayeux was the wife more danico of the Viking leader Rollo. She was the mother of William I Longsword and Gerloc, and grandmother of Richard the Fearless, who forged the Duchy of Normandy into a great fief of medieval France. Dudo of Saint-Quentin, in his panegyric of the Norman dukes, describes her as the daughter of a "Count Berengar", the dominant prince of that region, who was captured at Bayeux by Rollo in 885 or 889, shortly after the siege of Paris. This has led to speculation that she was the daughter of Berengar II of Neustria.
