List of North, Central American and Caribbean under-23 records in athletics

North, Central American and Caribbean U-23 records in the sport of athletics are the all-time best marks set in competition by an athlete who competes for a member nation of the North American, Central American and Caribbean Athletics Association (NACAC) by aged 22 or younger throughout the entire calendar year of the performance. Technically, in all under-23 age divisions, the age is calculated "on December 31 of the year of competition" to avoid age group switching during a competitive season. NACAC doesn't maintain an official list for such performances. All bests shown on this list are tracked by statisticians not officially sanctioned by the governing body.
