Mary of Clopas, the wife of Cleophas, was one of various Marys named in the New Testament.
Mary of Cleophas is explicitly mentioned only in John 19:25, where she is among the women present at the crucifixion of Jesus:
Now there stood by the cross of Jesus His mother, and His mother’s sister, Mary [the wife] of Clopas, and Mary Magdalene.
The expression Mary of Cleophas in the Greek text is ambiguous as to whether Mary was the daughter or wife of Cleophas, but exegesis has commonly favoured the reading "wife of Cleophas". Hegesippus thought that Cleophas was the brother of Saint Joseph.
