Dangereuse de l'Isle Bouchard (Poitevin: Dangerosa; 10791151) was the daughter of Bartholomew of l'Isle Bouchard and his wife Gerberge de Blaison. She was the maternal grandmother of the celebrated Eleanor of Aquitaine. She was also mistress to her granddaughters' paternal grandfather, William IX, Duke of Aquitaine. As the mistress of William the Troubadour, she was known as La Maubergeonne for the tower he built for her at his castle in Poitiers.

Dangereuse was a sobriquet she received for her seductiveness; her baptismal name may have been Amauberge.
