Ahijah the Shilonite (Hebrew: אחיה השילוני, Ahiya Hashiloni, "Yah is my brother") was a Levite prophet of Shiloh in the days of Solomon, as mentioned in the Hebrew Bible's 1 Kings. Ahijah encouraged a revolt against Solomon and foretold to Jeroboam that he would become king (I Kings, 11. 29).
The Hebrew Bible records two of his prophecies; 1 Kings 11:31-39, announcing the rending of the ten tribes from Solomon and 1 Kings 14:6-16, delivered to Jeroboam's wife, foretelling the death of the king's son, the destruction of Jeroboam's house, and the captivity of Israel "beyond the river."
According to 2 Chronicles, Ahijah also authored a book, described as Prophecy of Ahijah the Shilonite which contained information about Solomon's reign. This text, however, has not survived and is one of the lost texts mentioned in the Hebrew Bible. Rabbinic tradition credits Ahijah with having lived a very long life, linking his life-span with that of antediluvian patriarchs such as Methuselah and Noah.
