The Beauvau family was a historic family originating in Anjou. The Beauvau du Rivau branch was rooted in Brittany and produced two bishops of Nantes, whilst the Beauvau-Craon branch was established in Lorraine.

As with the comtes d'Anjou, the Beauvaus served the kings of France right up to the 18th century. In 1454, the family allied itself to the royal house of France by the marriage of Isabeau de Beauvau with Jean VIII de Bourbon-Vendôme
