Agnes of Rome (c. 291 - 304) was a Roman Christian adolescent who was executed for her faith in the 4th century. She is venerated as a virgin martyr and as a saint in the Catholic Church, Oriental Orthodox Church and the Eastern Orthodox Church, as well as the Anglican Communion and Lutheran Churches. She is one of several virgin martyrs commemorated by name in the Canon of the Mass, and one of many Christians martyred during the reign of the Roman emperor Diocletian.
