Castleton is a ghost town in the Castle Valley in southeastern Grand County, Utah, United States.

The community located on the La Sal Mountain Loop Road, some 18 miles (29 km) northeast of Moab.

The nearest inhabited town is Castle Valley, approximately 6 miles (9.7 km) to the northwest.

A short-lived gold placer mining camp existed here in the 1860s,[2] but the area was first settled by a prospector named Doby Brown in the late 1870s or early 1880s.

[3] In 1888 when a local gold rush began at nearby Miners Basin, Castleton became important as a supply town.
