Lamoni is a city in Decatur County, Iowa, United States.

[4] Lamoni is the home of Graceland University, affiliated with the Community of Christ, a denomination of the Latter Day Saint movement.

[6] In 1851, refugees from the Hungarian Revolution of 1848 sought to settle the area and form the community of New Buda (named for a neighborhood of Budapest).

[6] In 1870, Joseph Smith III authorized the Order of Enoch to purchase over 3,000 acres (12 km2) to form a community of the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church).

[7] The city was named after Lamoni, a king mentioned in the Book of Mormon.

[8] Members of the Church of Jesus Christ of Latter-day Saints, led by Brigham Young, passed through the community in 1846, staying at nearby Garden Grove, Iowa, while en route from Nauvoo, Illinois (where they had settled after being forced to leave Missouri), to the Salt Lake Valley.

[6] Lamoni was formally platted adjacent to newly laid tracks of the Chicago, Burlington and Quincy Railroad in 1879.

[8] In 1880, Smith moved to Lamoni (as did the RLDS Church headquarters) from Plano, Illinois.

After the Smith family moved to Independence to the area near Temple Lot in 1916, Liberty Hall served as a home for the aged, a farmhouse, a Civilian Conservation Corps (CCC) camp,[9] and a private residence before becoming a museum.

Lamoni remained the company's headquarters until 1945, when it moved to Chariton, Iowa.

The Lamoni area has a sizable Amish community, whose businesses are not open on Sundays.

32.3% of all households were made up of individuals, and 13.6% had someone living alone who was 65 years of age or older.

Jefferson Lines provides intercity bus service to Lamoni on a route between Minneapolis and Tulsa.
