List of Oceanian under-20 records in athletics

Oceanian junior records in the sport of athletics are ratified by the Oceania Athletics Association (OAA). 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.
