Fillmore is a city and the county seat of Millard County, Utah, United States. The population was 2,592 at the 2020 United States Census. It is named for the thirteenth US President Millard Fillmore, who was in office when Millard County was created by the Utah Territorial legislature.

History
Fillmore, located near the geographic center of the territory, was originally built as the capital of Utah Territory. The Utah Territorial Legislature approved a plan to locate the capital in the Pahvant Valley. On October 28, 1851, Utah governor Brigham Young chose the specific site for Fillmore. Jesse W. Fox, that same day, surveyed the town. Anson Call headed the colonizing company that shortly followed; they built houses, a grist mill, and a sawmill. The capitol building was begun in 1852.

In the following years, some disagreements developed with the Native Americans in the area, but Brigham Young sent Dimick B. Huntington to the area, and he managed to negotiate peace. The region was considered a route, along the 38th parallel, for the transcontinental railroad. Captain John W. Gunnison, leading a military party surveying the region, was attacked by a band of Pahvants (Ute) west of Fillmore. Gunnison and seven of his men were killed (October 1853). During the 1860s, two forts, Fort Deseret and Cove Fort were constructed nearby as protection from Indian unrest.

In 1855, the territorial legislature met in Fillmore. However, in 1856, the legislature decided to move the Territorial Capital to the larger community of Salt Lake City.
