2025 World Athletics Indoor Championships

The 20th World Athletics Indoor Championships was rescheduled to be held from 21 to 23 March 2025 in Nanjing, People's Republic of China at the newly built Nanjing's Cube gymnasium in the Nanjing Youth Olympic Sports Park. This would be the city's first hosting of the event although it staged the 2014 Summer Youth Olympic Games.

Nanjing was originally due to host an edition of the World Athletics Indoor Championships in 2020, then in 2021, and then again in 2023, with all these dates having to be postponed due to COVID-19 pandemic regulations in China. The 2022 edition took place in Belgrade, Serbia and the 2024 edition in Glasgow, United Kingdom.

Bidding process
On 26 November 2017, delegations from the three candidate cities made their presentations at the 212th IAAF Council Meeting: Nanjing, Serbia's capital Belgrade and Toruń, Poland. Nanjing won the bid for the 2020 World Athletics Indoor Championships.

Venue
The facility, a brand new purpose-built gymnasium at the Nanjing Youth Olympic Sports Park known as Nanjing's Cube will be the centrepiece of the event.
