Croydon[1] is an unincorporated community in northeastern Morgan County, Utah, United States.

Accessible from Interstate 84, it is home to Holcim's Devil's Slide Cement Plant and several hundred residents.

Lost Creek runs through this small unincorporated town, just northeast of the Devil's Slide rock formation.

Croydon was also home to the annual Widowmaker, a snowmobile and motorcycle hillclimbing contest founded in 1964.

The present name is after Croydon, in England, the native land of a large share of the first settlers.
