Irene of Thessalonica was an early Christian martyr born in Aquileia during the third century. According to tradition, she suffered martyrdom during the persecutions led by Emperor Diocletian. She was the sister of two other virgins, Agape and Chione. During her execution, she was wounded by arrows and subsequently burned at the stake. It is important to distinguish her from another martyr of the same name who lived in Constantinople.
