Ammon is a suburb city located directly between the Ammon foothills on the east and the city of Idaho Falls on the west, in Bonneville County, Idaho, United States. As of the 2010 US Census, the population of Ammon was 13,816.  Its estimated population as of 2017 is 15,540. 
Ammon was one of Idaho's fastest growing cities from 2000 to 2010. The City of Ammon experienced a 123.3% growth rate from 2000 to 2010 based on the 2010 US Census. Ammon is currently the 15th largest city in Idaho.
The City's rapid growth is due to the comfortable residential lifestyle, availability of affordable housing, and proximity to strong local job market.
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 Union Pacific 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 served by the Bonneville Joint School District #93. District #93 serves about 10,758 students in 19 schools, making it the fifth-largest by enrollment in the state of Idaho. The district has: 13 elementary schools serving students in K-6, two middle schools serving students in grades 7-8, and three high schools serving students in grades 9-12, along with an alternative high school.
