The 2023 AFC Asian Cup was the 18th edition of the AFC Asian Cup, the quadrennial international football tournament organised by the Asian Football Confederation (AFC). It involved 24 national teams after its expansion in 2019, with hosts Qatar the defending champions.

On 17 October 2022, the AFC announced that the tournament would be held in Qatar, replacing the original hosts China. Due to the high summer temperatures and Qatar's participation in the 2023 CONCACAF Gold Cup, the tournament was postponed to 12 January – 10 February 2024, while retaining the original name for both existing sponsorship and logistical purposes. The 2023 tournament were the second of three consecutive Asian Cup to be held in Middle East, following the 2019 AFC Asian Cup in United Arab Emirates and preceding the 2027 AFC Asian Cup in Saudi Arabia. This marked the first time a FIFA World Cup host nation hosts the AFC Asian Cup. Due to the one-year postponement, Qatar 2023 was the only tournament to have been held in an odd-numbered year since the 2007 edition.

Hosts and defending champions Qatar retained their title after defeating Jordan 3–1 in the final.
