Jehoshaphat, according to the Hebrew Bible, was the son of Asa, and the fourth king of the Kingdom of Judah, in succession to his father. His children included Jehoram, who succeeded him as king. His mother was Azubah. Historically, his name has sometimes been connected with the Valley of Josaphat.

Asa was, according to the Hebrew Bible, the third king of the Kingdom of Judah and the fifth king of the House of David. Based on the Biblical chronology, Biblical scholars suggest that he reigned from the late 10th to early 9th century BCE. He was succeeded by Jehoshaphat, his son. According to Edwin R. Thiele's chronology, when Asa became very ill, he made Jehoshaphat coregent. Asa died two years into the coregency.
