Job (Hebrew: ???????; Arabic: ?????? Ayyub) is the central character of the Book of Job in the Hebrew Bible. Job is also recognised as a prophet of God in the Qur'an.

The Book of Job begins with an introduction to Job's character. He is described as a blessed man who lives righteously. God's praise of Job prompts Satan to challenge Job's integrity and suggesting that Job serves God simply because he protects him. God removes Job's protection; allowing Satan to take his wealth; his children; and his physical health in order to tempt Job to curse God. Despite his difficult circumstances; he does not curse God; but rather curses the day of his birth. And although he protests his plight and pleads for an explanation; he stops short of accusing God of injustice. Most of the book consists of conversations between Job and his three friends concerning Job's condition and its possible reasons; after which God responds to Job and his friends.

The characters in the Book of Job consist of Job; his wife; his friends; a man named Eliyahu; God; and Satan. Neither the patriarchs nor any other biblical characters make an appearance.
