Johnson County Fairgrounds is the county fairground for Johnson County, at 633 N 1st St in Tecumseh. It is generally known locally as Johnson County Fairgrounds Park. 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 Johnson County, which handles entries, livestock identification and the certification a young person needs before showing an animal.
