Under-18 world best performances in the sport of athletics are the best marks set in competition by athletes aged 17 or younger throughout the entire calendar year of the performance. World Athletics (formerly IAAF) maintains an official list for such performances, but only in specific outdoor and indoor events. All other records shown on this list are tracked by statisticians not officially sanctioned by the world governing body. These age category records were formerly called world youth bests.
