María de Jesús was a Spanish Discalced Carmelite nun who lived from 1560 to 1640. Born into a wealthy family in Tartanedo, she chose a life of simplicity and entered the religious order in Toledo at age seventeen. During her time in the convent, she served multiple terms as prioress and maintained a close friendship with Teresa of Avila. Despite facing a period of isolation following an unjust accusation in 1600, she remained composed and eventually regained her position within the community.
