According to the Book of Mormon, the land of Jershon (/ˈdʒɛr.ʃɑːn/) was located on the east by the sea, south of the land Bountiful.
We first hear of Jershon in the book when the people of Ammon, seeking protection from their fellow Lamanites, resettle there about 76 BC (). Because of the threat of war from the Zoramites in Antionum to the south, the Ammonites were relocated to Melek about 73 BC. All the references to Jershon come from this three- to four-year period.
