The Minor Prophets (also called the Twelve Prophets), in Hebrew תרי עשר (tərê ʿaśar, 'the twelve' in Aramaic), in Greek Μικροί προφήτες (mikròi profétes, 'minor prophets') or Δωδεκαπροφήτον (Dodekaproféton, 'twelve prophets'), are the authors of twelve prophetic books in the Old Testament of the Christian Bible.

They are defined as "minor" because of the brevity of their books as opposed to those of the other authors of prophetic books, called major: Isaiah, Jeremiah, Ezekiel and Daniel.

The order of the twelve books is: Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah and Malachi.
