The 2023 World Athletics Championships (Hungarian: 2023-as atlétikai világbajnokság), the nineteenth edition of the World Athletics Championships, were held from 19 to 27 August 2023 at the National Athletics Centre, in Budapest, Hungary. The tournament returned to its usual two-year cycle after the previous event in Eugene, Oregon, United States was postponed to 2022, held 13 months earlier due to the COVID-19 pandemic.

These are the first World Athletics Championships in Hungary. The city of Budapest had previously stated an interest in hosting the 2007 World Championships, but withdrew and it was eventually held in Osaka.

The championships were held in the National Athletics Centre in Budapest, which was specially built for this event, and has a provisional capacity of 36,000.

The official mascot of the event is a Racka, called Youhuu.

World Athletics announced that athletes would qualify by their World Athletics Rankings position, wild card (reigning world champion or 2022 Diamond League winner) or by achieving the entry standard.

To qualify as a Wild Card required fulfilling one of the following conditions:

Countries who had no male and/or no female athletes who had achieved the Entry Standard or considered as having achieved the entry standard or a qualified relay team, could enter one unqualified male athlete OR one unqualified female athlete in one event of the championships (except the road events and field events, combined events, 10,000 m and 3000 m steeplechase).

Since the postponement of the 2023 World Relays to 2024 Nassau, for Covid-pandemic reasons, a modified qualification system has been available for relay teams.
