William X (1099 – 9 April 1137), called the Saint, was Duke of Aquitaine, Duke of Gascony, and Count of Poitou (as William VIII) between 1126 and 1137. He was the son of William IX by his second wife, Philippa of Toulouse.

William was born in Toulouse during the brief period when his parents ruled the capital. His birth is recorded in the Chronicle of Saint-Maixent for the year 1099: Willelmo comiti natus est filius, equivoce Guillelmus vocatus ("a son was born to Count William, named William like himself"). Later that same year, much to his wife's ire, Duke William mortgaged Toulouse to Philippa's cousin, Bertrand of Toulouse, and then left on Crusade.

Philippa and her infant son were left in Poitiers. Long after Duke William's return, he took up with Dangerose, the wife of one of his vassals, and set aside his rightful wife, Philippa. This caused strain between father and son, until William married Aenor de Châtellerault, daughter of his father's mistress, in 1121.

He had three children with her:

He possibly had one natural son, William. For a long time it was thought that he had another natural son called Joscelin and some biographies still erroneously state this fact, but Joscelin has now been shown to be the brother of Adeliza of Louvain. The attribution of Joscelin as a son of William X has been caused by a mistaken reading of the Pipe Rolls pertaining to the reign of Henry II, where 'brother of the queen' has been taken as Queen Eleanor, when the queen in question is actually Adeliza of Louvain. William, called of Poitiers in the Pipe rolls may have been a half brother of Eleanor. Chronicler John of Salisbury tells us that Petronella died in 1151 or 1152, after which her husband Raoul of Vermandois briefly remarried.

William was both a lover of the arts and a warrior. He became involved in conflicts with Normandy (which he raided in 1136, in alliance with Geoffrey V, Count of Anjou who claimed it in his wife's name) and France.

Even inside his borders, William faced an alliance of the Lusignans and the Parthenays against him, an issue resolved with total destruction of the enemies. In international politics, William X initially supported antipope Anacletus II in the papal schism of 1130, opposite to Pope Innocent II, against the will of his own bishops. In 1134 Saint Bernard of Clairvaux convinced William to drop his support to Anacletus and join Innocent.

In 1137 William joined the pilgrimage to Santiago de Compostela, but died of suspected food poisoning during the trip. On his deathbed, he expressed his wish to see king Louis VI of France as protector of his fifteen-year-old daughter Eleanor, and to find her a suitable husband. Louis VI naturally accepted this guardianship and married the heiress of Aquitaine to his own son, Louis VII.
