The House of Beaumont was one of the great Anglo-Norman baronial noble families, who became rooted in England after the Norman Conquest.

Roger de Beaumont, Lord (seigneur) of Pont-Audemer, of Beaumont-le-Roger, of Brionne and of Vatteville, was too old to fight at the battle of Hastings and stayed in Normandy to govern and protect it while William was away on the invasion.

His brother Henri de Beaumont was created Earl of Warwick.

Counsel from the Beaumonts was important to the Dukes of Normandy, then by the kings of England.

The French family came to England in the late 14th century (see Isabella de Vesci) and modern Beaumonts are descended from her brother Henry de Beaumont who was the first of the English barony and later Viscounts.
