Euphemia of Chalcedon was a Christian virgin and martyr born in 289. As the daughter of a senator named Philophronos, she lived in Chalcedon during the early 4th century. She is recognized as a great martyr for her refusal to perform sacrifices to the god Ares. This act of faith led to her death in 304, when she was martyred by a bear. Her life and steadfastness have led to her commemoration across several Christian traditions.
