Athaliah was the daughter of either king Omri, or of King Ahab and Queen Jezebel of Israel, the queen consort of Judah as the wife of King Jehoram, a descendant of King David, and later queen regnant c. 841–835 BCE.

Omri was, according to the Hebrew Bible, the sixth king of Israel. He was a successful military campaigner who extended the northern kingdom of Israel. Other monarchs from the House of Omri are Ahab, Ahaziah, Joram, and Athaliah. Like his predecessor, king Zimri, who ruled for only seven days, Omri is the second king mentioned in the Bible without a statement of his tribal origin. One possibility, though unproven, is that he was of the tribe of Issachar.
