Constance of Castile (1136 or 1140 – 4 October 1160)[1] was Queen of France as the second wife of Louis VII, who married her following the annulment of his marriage to Eleanor of Aquitaine.

[2] She was a daughter of Alfonso VII of León and Berengaria of Barcelona,[3] but her year of birth is not known.

The official reason for her husband's annulment from Eleanor of Aquitaine had been that he was too close a relative of Eleanor for the marriage to be legal by Church standards; however, he was even more closely related to Constance.

Constance died giving birth to her second child.

Desperate for a son, her husband remarried a mere five weeks after her death.
