The Epistle of James (Ancient Greek: Ἰάκωβος Iakōbos), the Book of James, or simply James, is one of the twenty-two epistles (didactic letters) in the New Testament.

The author identifies himself as "James, a servant of God and of the Lord Jesus Christ," who is writing to "the twelve tribes scattered abroad" (James 1:1). The epistle is traditionally attributed to James the Just, and the audience is generally considered to be Jewish Christians who were dispersed outside of Palestine due to persecution.
