Saint Aurelia Petronilla is an early Christian saint. She was venerated as a virgin martyr by the Catholic Church. She died in Rome at the end of 1st century, or possibly in the 3rd century.
Petronilla, her name is the feminine and diminutive of Peter, and is traditionally identified as the daughter of Saint Peter, though this may stem simply from the similarity of names. It is believed she may have been a convert of the saint (and thus a "spiritual daughter"), or a follower or servant. It is said that Saint Peter cured her of palsy.

Roman inscriptions, however, identify her simply as a martyr. She may have been related to Saint Domitilla.
