Mary of Jesus de León y Delgado was a 17th-century Spanish mystic and Dominican lay sister from the Canary Islands. Born in El Sauzal in 1643, she entered a Dominican convent in 1668. She spent much of her life in San Cristóbal de La Laguna, where she was known for her visionary experiences. During her life, she reportedly experienced phenomena such as levitation, bilocation, and stigmata near her heart. She died in 1731 and is currently recognized as a Servant of God.
