Joan of Artois, Countess of Foix

Joan of Artois (1289–after 1350), countess of Foix and viscountess of Béarn, was the sister of Robert III. She lost her father Philip of Artois in 1298. Her marriage to Gaston, eldest son of Count Roger Bernard III of Foix, was agreed with Philip IV in 1299 and contracted at Senlis in 1301, and when Gaston succeeded in 1302 she became countess.

Her influence over her husband brought repeated clashes with the Foix nobility, who in 1317 petitioned the Parlement to remove her from the care of her children, accusing her of extravagance and dissolute living.

In 1331 Philip VI let her son Gaston II imprison her, at Foix and then Orthez. She was freed in 1347 at the request of her son Robert, bishop of Lavaur, and retired to Carbonne.
