In the Book of Mormon, Lamoni (/ləˈmoʊnaɪ/)[1] is king of the land of Ishmael, part of territory controlled by the Lamanites.

Eventually Lamoni helps gain freedom for Ammon and his fellow Nephite missionaries to preach freely in the Lamanite areas.

At Ammon's word, the king revives and talks of Jesus, he and the queen are overwhelmed with joy, and they both fall down as if dead.

[5] In The Annotated Book of Mormon, Grant Hardy points out that Lamoni may have been politically motivated to offer his daughter as a wife to Ammon.

[6] Fatimah Salleh and Margaret Olsen Hemming point out that while the Lamanites are often described as passing down bad traditions and lacking a relationship with God, the way Lamoni and his wife talk about the Great Spirit implies they have at least limited religion of some sort, as well as knowledge and interaction with God.

It was originally named New Buda by Hungarian immigrants, but in 1870, Joseph Smith III renamed the settlement "Lamoni" after him.
