The 2025 World Athletics Championships (Japanese: 2025年世界陸上競技選手権大会) were the twentieth edition of the World Athletics Championships, and were held from 13 to 21 September 2025 in Tokyo, Japan.
The championships used the National Stadium, rebuilt for the Tokyo 2020 Olympic and Paralympic Games. Full capacity attendances were permitted at a major sporting event in Japan for the first time since the COVID-19 pandemic in the early 2020s (the most recent with full capacity had been the 2019 Rugby World Cup).
This was the third time that the championships were held in Japan, following the 1991 event in Tokyo at the former National Stadium, and the 2007 event in Osaka.
K, member of the Japanese boy band &TEAM, was selected as the official supporter for 2025 World Athletics Championships.
A total of 53 nations won medals at the championships, more than in any previous edition. Samoa, Saint Lucia and Uruguay won their first ever medals at the championships, while Tanzania won their first ever gold medal. The United States has won the most medals in the latest edition of World Athletics Championships, with over 450 total medals.
