The following are the national records in track and field in the United States. Some of the records are maintained by USA Track & Field (USATF). Outdoor times for track races between 200 meters to 10,000 meters are set on 400-meter unbanked tracks. Indoor marks are established on 200-meter tracks, banked or unbanked. Indoor tracks longer than 200 meters are considered "oversized" and times are not accepted for record purposes. Indoor sprint races are held on level straight-aways.
