Saint Dorothy is a 4th-century virgin martyr who was executed at Caesarea Mazaca. Evidence for her actual historical existence or acta is very sparse. She is called a martyr of the late Diocletianic Persecution, although her death occurred after the resignation of Diocletian himself. She should not be confused with another 4th-century saint, Dorothea of Alexandria.
She and Theophilus are mentioned in the Roman Martyrology as martyrs of Caesarea in Cappadocia, with a feast day on 6 February. She is thus officially recognized as a saint, but because there is scarcely any non-legendary knowledge about her, she is no longer included in the General Roman Calendar.
