What is the name of David's wife in the Bible?

King David did not have one wife. Back in those days men had a number of wives, especially men of royalty or upper class. David had a total of 7 wives and a number of concubines.

The names of his wives are: Abigail, Abital, Ahino-am, Elgah, Haggith and Maacah. Later, David would commit adultery with Bathsheeba while her husband Uriah the Hittite was off fighting for David. The King would have Uriah sent into fierce battle until he was killed and then he married Bathsheeba as she was pregnant with King David's child.
