Uzziah (Hebrew meaning: Yahweh is my strength), also known as Azariah, is the king of the ancient Kingdom of Judah, and one of Amaziah's sons, whom the people appoint to replace his father (2 Kings 14:21; 2 Chronicles 26:1).

(According to the Catholic Encyclopedia, the second form of his name most likely results from a copyist's error.)

He is one of the kings mentioned in the genealogy of Jesus in the Gospel of Matthew.

Uzziah is sixteen when he becomes king of Judah and reigns for fifty-two years.

William F. Albright has dated his reign to 783 – 742 BCE.

Edwin R. Thiele's chronology has Uzziah becoming coregent with his father Amaziah in 792/791 BCE, when Amaziah is struck with leprosy for disobeying the Lord (2 Kings 14:5), with his sole reign starting on the death of his father in 768/767 BCE.

Thiele dates Uzziah's being struck with leprosy to 751/750 BCE, at which time his son Jotham takes over the government, with Uzziah living on until 740/739 BCE.

Pekah becomes king of Israel in the last year of Uzziah's reign.

The Catholic Encyclopedia dates his reign from 809-759 BCE.
