Eleanor of Comminges, Countess of Foix

Eleanor of Comminges (born before 1300, died c. 1369) was the mother of Gaston III of Foix, later famous as Fébus. A daughter of Bernard VII, Count of Comminges, she seemed destined to stay unmarried or enter a convent until her uncle arranged her marriage in 1324 to Gaston II, Count of Foix, then fourteen; she was about twice his age. After several children died young, she bore Gaston III in 1331.

Gaston II died in 1343 at the siege of Algeciras, and Eleanor became tutor and regent of Foix-Béarn, lands owing homage to both the French and English kings.

She led her twelve-year-old son on a tour of 126 places to introduce him to his subjects. He came of age in 1345, but she kept managing his property until he turned twenty-one, and died near Le Mas-d'Azil.
