Ralph I, Count of Vermandois

Ralph I of Vermandois (French: Raoul I^er) (d. 14 October 1152) was Count of Vermandois. He was a son of Hugh, Count of Vermandois and his wife, Adelaide, Countess of Vermandois.Template:Sfn Ralph was a grandson of Henry I of France, while Ralph's mother had been the Carolingian heiress to Herbert IV, Count of Vermandois.

Ralph's paternal uncle was Philip I of France. Through him Ralph was a first cousin of Louis VI of France and a first cousin once removed of Louis VII of France.

Ralph served as the seneschal of France during the reign of Louis VI.Template:Sfn Under pressure from the queen, Eleanor of Aquitaine, Louis allowed Ralph to repudiate his wife, Eleanor of Champagne, sister of Stephen, King of England, in favor of Eleanor of Aquitaine's sister, Petronilla of Aquitaine.Template:Sfn This led to a war with Theobald II of Champagne, who was the brother of Ralph's first wife Eleanor. The war lasted two years (1142–44) and ended with the occupation of Champagne by the royal army.

Ralph and Petronilla were excommunicated by Pope Innocent II for a marriage deemed illegitimate, overriding three bishops who had already annulled Ralph's prior marriage.Template:Sfn With Eleanor's death in 1147, the following year Pope Eugene III, legitimized the marriage at the Council of Reims.Template:Sfn
