How Many Wives Did Joseph Have In The Bible?
If you are talking about Jacob (Israel)’s son Joseph, then he had one wife.
Genesis 41:45 says that after Joseph interpreted the dreams of Pharaoh 45 … Pharaoh called Joseph’s name Zaphnath-paaneah; and he gave him to wife Asenath the daughter of Potipherah priest of On. And Joseph went out over all the land of Egypt. (King James Version)
Joseph had two sons with Asenath: Manasseh and Ephraim.
If you are talking about Joseph the (earthly/ foster) father of Jesus, then, again, he had one wife: Mary. You can read about them in chapters 2 of Luke’s gospel and the first two chapters of Matthew’s gospel.
Joseph and Mary had children together including James, Joses (Joseph), Jude and Simon, as well as unnamed sisters (Mark 6:3, Matthew 13:55–56; see also Mark 3:31–33, Galatians 1:19, and 1 Corinthians 9:5)
If you are talking about Joseph of Arimathea, then it’s never explicitly stated whether he was married, although it would be logical to assume such a wealthy man would have had a wife and children.
I’m not sure if there are other Joseph’s in the Bible to whom you could be referring, but these are the three that come to mind.
