Beaugency (French pronunciation: [boʒɑ̃si] ⓘ) is a commune in the Loiret department, Centre-Val de Loire, north-central France.

The massive original keep is today a ruined shell, surrounded by a mansion built later on in the 14th century.

He was also granted lands in Yorkshire, England by William the Conqueror and some of his decedents settled there and became the Fletcher family.

In 1080 he goes on a pilgrimage to Rome and his son, Ralph ruled the lordship of Beaugency in his absence.

This practice was also carried out by other prominent noble families linked to Vermandois, including Ralph I's brother in laws Robert de Beaumont, 1st Earl of Leicester and afterwards William de Warenne, 2nd Earl of Surrey on their marriage to his wife's younger sister, Elizabeth of Vermandois, Countess of Leicester.

The Arms used by the de Warenne Earl of Surrey are quartered and are still used by their relations, the Dukes of Norfolk.

On 16 September 1944, German Major General Botho Henning Elster and his 18 850 men and 754 officers surrendered at the Loire bridge of Beaugency to the U.S. Army after being harassed and surrounded by the French Résistance.
