Ammon was founded by members of The Church of Jesus Christ of Latter-day Saints in 1888. It was originally called South Iona because it was the dependent branch in the south end of the Iona, Idaho ward. The area was made a ward in the church in 1889 with Arthur M. Rawson as bishop, who renamed the town in honor of Ammon, a figure in the LDS book of scripture, the Book of Mormon. Since it was now independent of the Iona Ward, a new name seemed appropriate. On February 9, 1893, the name of the town was changed from South Iona Ward to Ammon.

By 1930 the village of Ammon had 270 inhabitants, but the total district of Ammon, which is how the name is usually used and is closer to the modern borders, had a population of about 1100.

Ammon was an early agricultural center and later was home to several general stores, a grain elevator and a brickyard. The city was officially incorporated on October 10, 1905. It became a Second Class City under Idaho law in 1963. In the early 1900s a spur line was built by the Eastern Idaho Railroad to the Ammon Elevator. Beginning in the 1940s housing divisions have aided the city's growth and it has become a suburb for the adjacent city of Idaho Falls. Building boomed in the 1990s in both the business and housing sectors, and the city was one of the fastest growing in Idaho from 2000 to 2010.


Ammon is located at 43°28′35″N 111°58′5″W / 43.47639°N 111.96806°W / 43.47639; -111.96806 (43.476268, -111.967964).

According to the United States Census Bureau, the city has a total area of 7.27 square miles (18.83 km2), of which, 7.26 square miles (18.80 km2) is land and 0.01 square miles (0.03 km2) is water.
