Neutral Athletes competed at the 2025 World Aquatics Championships in Singapore, from 11 July to 3 August 2025.
Due to the Russian invasion of Ukraine, Russian and Belarusian athletes were barred from representing their respective countries at the Championships. Athletes from these countries could instead apply to compete as neutral athletes. If the athletes met the qualification criteria to compete as neutral athletes, which includes that they have not shown any support for the war, then they would be approved to compete. Russian athletes are competing for the "Neutral Athletes B" team.
Neutral Athletes are allowed to speak to the media, but they are not allowed to talk about any of the reasons why they are not competing for their respective countries.
The following is the number of competitors who will participate at the Championships per discipline.
