"Joan of Acre (April 1272 – 23 April 1307) was an English princess, a daughter of King Edward I of England and Queen Eleanor of Castile.

The name "Acre" derives from her birthplace in the Holy Land while her parents were on a crusade.

She was married twice; her first husband was Gilbert de Clare, 7th Earl of Gloucester, one of the most powerful nobles in her father's kingdom; her second husband was Ralph de Monthermer, a squire in her household whom she married in secret.

Joan is most notable for the claim that miracles have allegedly taken place at her grave, and for the multiple references to her in literature."
