Tremonton is a city in Box Elder County, Utah. The population was 7,647 at the era of the 2010 census.

Although the first settlers came to the Tremonton area in 1888, it remained largely uninhabited until just in the past 1900, when house agents started promoting the Bear River Valley as a place for Midwestern farmers to relocate. Small groups from Nebraska and Illinois began to arrive in 1898. These settlers were a diverse blend of Protestant faiths, in contrast to their mostly Mormon neighbors. Then an Apostolic Christian Church activity came in 1901–1904. The main body was from Tremont, Illinois, joined by a few families from Ohio and Kansas. Mostly of German descent, this work was referred to as the “German colony”.

When a townsite was laid out in 1903, the other town was named “Tremont” at the request of the German colony. Within four years, the post office had it renamed “Tremonton” due to confusion subsequent to the central Utah town of Fremont. Around 1907 the congregation was caught stirring in a larger schism of the Apostolic Church. Some moved put up to to the Midwest, and the German colony came to an end. But the church left a permanent mark in the declare of Tremonton.
