Cheyenne County Fairgrounds is the county fairground for Cheyenne County, at 10955 US Hwy 30 in Sidney. Like most Nebraska fairgrounds it is owned by the county agricultural society and is in use well beyond fair week — rodeos, horse shows, tractor pulls, sales and community events. The 4-H side of the county fair is run by Nebraska Extension in Cheyenne County, which handles entries, livestock identification and the certification a young person needs before showing an animal.
