Jeconiah (also known as Jehoiachin, Joachin, and Coniah) was king of Judah. He was the son of Jehoiakim and Nehushta, daughter of Elnathan of Jerusalem. Both Albright and Thiele date his reign to 598 BC. He began to reign in Jerusalem at the age of eight, upon the death of his father, Jehoiakim. His children included Assir and Salathiel.

After reigning for three months and ten days, he was removed from office by the Babylonians, and Zedekiah was placed as king in Jerusalem (2 Chronicles 36:9). Jeconiah, with his household, many of the rulers of Judah, and many craftsmen, were taken captive to Babylon. Cuneiform records dated to 592 BC mention Jeconiah ("Ia-'-ú-kinu") and his five sons as recipients of food rations in Babylon. He was still called king while in captivity.

In the thirty-seventh year of his captivity (562 BC), he was removed from prison by Amel-Marduk, King of Babylon.
