There are exactly three places in the world officially named "Bountiful":
All three trace to the Book of Mormon (Alma 27:22), where "Bountiful" describes a fertile, blessed land. Latter-day Saint settlers applied the name to new communities in the Intermountain West and Canada.
Despite the name's positive connotations, no other incorporated cities, towns, or census-designated places in the US, Canada, or globally carry the name "Bountiful" officially.
