Hildale is a city in Washington County, Utah, United States. The population was 2,726 at the 2010 census.

Hildale is a twin city to the better-known Colorado City, Arizona, which together straddle the border between Utah and Arizona. Hildale is the headquarters of the Fundamentalist Church of Jesus Christ of Latter Day Saints. Many adults in the community practice plural marriage. The United Effort Plan, the financial arm of the FLDS owns most of the property in the city. Since most government officials — including the police force — are FLDS members, some critics have likened the community's atmosphere to that of a prison.
