Hildale is a city in Washington County, Utah, United States. The population was 1,127 at the 2020 census.

Hildale is located on the border of Utah and Arizona. It is notable for its history as a colony of Mormon polygamists.

Hildale, formerly known as Short Creek Community, was founded in 1913 by members of the Council of Friends, a breakaway group from the Salt Lake City–based Church of Jesus Christ of Latter-day Saints (LDS Church). Hildale and its border city of Colorado City, Arizona, have an interwoven history with their shared claims of "Short Creek."

In 1914 a small school was built, followed by a post office. Much of Hildale's history is wrapped up in its association with the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS), and two additional polygamist breakoffs. Throughout the majority of its history, community members faced scrutiny and government intervention. In 1953 Arizona Governor John Howard Pyle ordered a raid of the surrounding community which led to many arrests. The following year, the Utah government attempted the same. The two events are collectively known as The Short Creek raids. Utah continued its enforcement by separating children from Families, starting with the family of Vera Black.

The FLDS church's private trust, which evolved into a charitable trust, was the United Effort Plan. A major component of that trust included members of the church "consecrating", or donating, their property to the trust, with the understanding it would be put to its best use. Because of this practice, and increasing wealth that the trust purchased property, a vast majority of the real property in Hildale was controlled by single legal entity which wielded quite a bit of power, and influenced land-use decisions. The majority of the area was developed as very low-density, with large homes to accommodate complex family structures, and a great deal of agricultural land. After the trust's control was taken by Utah in 2005, then transitioned back to a board, the large square footage homes that originally housed multiple families, has complicated the homes being transitioned back for private use.

Hildale eventually incorporated as a town in 1963, and a city in 1990.

In January 2004 Warren Jeffs, the Prophet of the FLDS church and a major community leader, consolidated power within the UEP, and the church. This included the excommunication of many male members of the faith group, who were then expected to leave the community immediately, since their land and homes were operated by the Trust. While this practice had affected the city in small numbers before, this singular event led to increased attention to the community, and scrutiny of the Trust's control. When Jeffs was later accused of federal crimes in 2005, and became a fugitive, the Utah attorney general's office temporarily seized control of the assets of the Trust (which also included land in Arizona, Texas, British Columbia and elsewhere.)

On April 6, 2010, Arizona officials executed search warrants at governmental offices of the towns of Colorado City, Arizona and Hildale, Utah. According to one report, the warrants involved the misuse of funds and caused the Hildale Public Safety Department to be shut down. According to another report, city personnel and volunteers were ordered out of the buildings while the search was being conducted, prompting protests from Colorado City Fire Chief Jake Barlow. Then in June 2014, the Arizona Office of the Attorney General filed a motion in U.S. District Court seeking to dissolve the local police forces and "the disbandment of the Colorado City, Arizona/Hildale, Utah Marshal's Office and the appointment of a federal monitor over municipal functions and services." As the basis for the legal proceeding, the Arizona Attorney General stated that "[t]he disbandment of the Colorado City/Hildale Marshal's Office is necessary and appropriate because this police department has operated for decades, and continues to operate, as the de facto law enforcement arm of the FLDS Church."
