The Devereaux House in Salt Lake City, Utah, United States, also known as the Staines-Jennings Mansion, was built in 1857 for William Staines.

It was a social center for the area, and was the scene of a meeting between Brigham Young and Governor Alfred Cumming to resolve the Utah War.

Jennings, believed to be the Salt Lake Valley's first millionaire, named the house "Devereaux" for a family property at Yardley, Birmingham in England.

Following Jennings' death in 1886 the house passed through several hands, and was at one time an alcohol treatment facility, the Keely Institute.

[2] The State of Utah acquired the property in the 1970s and approved the use of public funds to restore it in 1978, but a tragic fire in 1979 almost resulted in its demolition.

The Church of Jesus Christ of Latter-day Saints acquired it in 2005 and maintains it as a historic site with occasional use for receptions and other events.
