Maria of Aragon (Spanish: María de Aragón) (1396–1445) was the first wife and Queen consort of John II of Castile. The daughter of Ferdinand I of Aragon and Eleanor of Alburquerque, she married her cousin John in 1420.


Maria was married by her brother in his ambition to place his father's issue on the thrones of the Spanish nations. The marriage took place in simplicity due to the difficult political situation. Queen Maria was occasionally politically active on behalf of her brothers, the princes of Aragon; she disregarded her husband's policy in favor of her brothers and the relationship between Maria and John was somewhat tense.

Maria had four children:

After her death in 1445, her husband married Isabella of Portugal and they became the parents of Isabella I of Castile. Maria has no descendants today, her line having gone extinct within a few decades of her death.
