# List of African under-20 records in athletics

African Junior Records in the sport of athletics are ratified by the Confederation of African Athletics (CAA). Athletics records comprise the best performance of an athlete before the year of their 20th birthday. Technically, in all under 20 age divisions, the age is calculated "on December 31 of the year of competition" to avoid age group switching during a competitive season. CAA doesn't maintain an official list for indoor performances. All bests shown on the indoor list are tracked by statisticians not officially sanctioned by the governing body.
