The House of Nesle is a feudal family that spawned a long line of Counts of Soissons and eventually merged with the House of Clermont. Nesle is a commune in northern France near Saint-Quentin, Aisne.

With the marriage of Gertrude and Raoul, the houses of Nesle and Clermont were united, and sometimes referred to as the House of Clermont-Nesle.
In addition to the Clermont lineage, the son of John and Elizabeth, Raoul de Nesle, also achieved fame. Raoul married Alix de Roye, widow of John III, Count of Alençon. Their son was John I de Nesle, who married Joan, Countess of Ponthieu, widow of Ferdinand III, King of Castile. The youngest daughter of Raoul and Alix, Marie, married John II, Seigneur d’Agimont, son of John I, Count of Looz and Chiny, and his second wife Isabelle de Condé. Drogo of Nesle and Ralph, Lord of Soissons, are likely related to the house but precise relationships are unknown.
