The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings, the rule change still uses existing marks. Not all governing body jurisdictions have adopted the rule change.

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.
