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.

The Kingdom of Judah was an Israelite kingdom of the Southern Levant during the Iron Age. Centered in the highlands of Judea, the landlocked kingdom's capital was Jerusalem. Jews are named after Judah, and primarily descend from people who lived in the region.
