Crook County was formed in 1875 from Albany and Laramie Counties, although it wasn't organized until 1888. It was named for Brigdier General George Crook, a commander in the Indian Wars. In 1890, Crook County was split to form Weston County and in 1911, it was split again to form Campbell County. Sundance is the county seat.

Crook County is bordered on the east by Butte County, South Dakota, Lawrence County, South Dakota, on the south by Weston County, Wyoming, on the west by Campbell County, Wyoming and to the north by Powder River County, Montana and Carter County, Montana. Crook County was formed from Laramie County and Albany County. For information before 1875, please refer to these two counties to locate records.
