Aurea of Ostia was a third-century Christian martyr, possibly of noble or royal descent, who lived in Ostia. Following her exile from Rome due to her faith, she resided on an estate outside the city walls where she supported the local Christian community. During the mid-third century, she was executed for refusing to perform sacrifices to Roman deities. Her death occurred during the reign of either Trebonianus Gallus or Claudius Gothicus, and she is recognized as the patron saint of Ostia.
