The House of Bellême also referred to as the Family of Bellême was an important seigneurial family during the 10th through the 12th centuries. Members of this family held the important castles of Bellême, Alençon, Domfront and Sées as well as extensive lands in France, Normandy and Maine.

Bellême is a commune in the Orne department in northwestern France. It is classed as a Petites Cités de Caractère. The musicologist Guillaume André Villoteau (1759–1839) was born in Bellême, as was Aristide Boucicaut (1810-1877), owner of Le Bon Marché, the world's first department store. This town is possibly the origin of the English and French surname Bellamy.
