Infanta Isabella of Castile (1283–1328), Viscountess of Limoges, was the first Queen consort of James II of Aragon and the second wife of John III, Duke of Brittany.
Isabella was born in Toro, the eldest daughter of Sancho IV of Castile and María de Molina. On 1 December 1291, Isabella married James II of Aragon in the city of Soria. The bride was only eight years old and the groom twenty-four. The marriage was never consummated.
Sancho IV died on 25 April 1295. James chose to change his alliances and take advantage of the turmoil inside Castile. He had their wedding annulled and proceeded to marry Blanche of Anjou, second daughter of Charles II of Naples and Maria Arpad of Hungary.
Isabella remained unwed for about a decade. In 1310, at Burgos, she married her second husband John III, Duke of Brittany. There were no children from this marriage. She was buried at Priere.
