Ammon, also referred to as the Ammonites and children of Ammon, is an ancient nation described in the Old Testament to be located east of the Jordan River, Gilead, and the Dead Sea, in present-day Jordan.

The chief city of the country is Rabbah or Rabbath Ammon, site of the modern city of Amman, Jordan's capital.

Milcom and Molech (who may be one and the same) are named in the Bible as the gods of Ammon.
