List of United States youth records in track and field

United States Youth records in athletics are the best marks set in an event by an American athlete who will not reach their 18th birthday in the given year of competition. USATF, the United States governing body, does not keep records for the youth division. This list is compiled from IAAF lists and corresponds to IAAF definitions of the age division. USATF keeps outdoor youth division records here, but the age divisions do not correspond with IAAF divisions and records mostly outdated. A youth could be in the USATF 17-18 year division, but not qualify under the IAAF definition. Additionally, USATF rules limit eligibility for youth records to youth competitions, while IAAF accepts any performance by a qualified athlete in a properly conducted meet. Track and Field News also keeps only outdoor records and in many cases their records do not agree with USATF. All indoor records shown on this list are tracked by statisticians not officially sanctioned by the governing body.
