# List of South American under-23 records in athletics

South American U23 records in the sport of athletics are ratified by the Atletismo Sudamericano, which maintains an official list for such performances, but only in a specific list of outdoor events. Athletics records comprise the best performance of an athlete before the year of their 23rd birthday. 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.
