Isabella (Catalan: Elisabet) (1337 – 1406) was the last titular Queen of Majorca and Countess of Roussillon and Cerdanya from 1375 to her death.

She was the daughter of James III and his first wife, Constance of Aragon. Her maternal grandparents were Alfonso IV of Aragon and his first wife Teresa of Entença and Antillon d'Urgell, countess of Urgell, vescomtess of Àger, Co-princess of Andorra.

She succeeded to the titles and pretensions for the Kingdom of Majorca, as well as the actual lands, of her brother James IV on his death in 1375. Their father had lost the kingdom (1343) and he died in the Battle of Llucmajor (1345) by Peter IV of Aragón. Isabella was unable at any point to mount a serious attempt to regain her claimed territories. In her attempt to reclaim the throne, she adopted two men as sons and to fight for her in front of the Aragonese King, her uncle Peter IV of Aragon. She died in France about 1406.

On 4 September 1358, Isabella married the John II, Marquess of Montferrat in Montpellier. They had five children:

Otto III of Montferrat (1358-1378)

John III of Montferrat (1360-1381)

Theodore II of Montferrat (1364-1418)

William (1365-1400)

Margareth(c. 1365-1420), married in 1375 to Peter II of Urgell

On 1375 she married with Baron Konrad von Reischach zu Jungnau. They had one boy:

Baron Michael von Reischach zu Jungnau.

Her children did not accept to be kings of Majorca but her only one daughter, Margareth accepted to reclaim to Aragon her pretensions to be the mother of the future king of Majorca, for her son, count James II of Urgell.
