The 4×100 metres relay at the World Championships in Athletics has been contested by both men and women since the inaugural edition in 1983. It is the second most prestigious title in the discipline after the 4×100 metres relay at the Olympics. The competition format typically has one qualifying round leading to a final between eight teams. As of 2015, nations can qualify for the competition through a top eight finish at the previous IAAF World Relays event, with the remaining teams coming through the more traditional route of ranking highly on time in the seasonal lists. This system was modified due to the postponement of 2023 World Athletics Relays to 2024: therefore, the eight teams directly qualified are those of the 2022 World Championships, in Eugene, completed by eight more 2022-2023 top lists' teams.
