The United States, the strongest and deepest swimming country in the world, is expected to enter the maximum number of athletes into each event of the Olympic swimming program: 56 spots in individual and seven relay teams. Of course, many swimmers will compete in multiple events, reducing the total number of individual athletes on the U.S. Olympic swimming team.

The team will come together during the U.S. Olympic Team Trials taking place June 13-20. The Trials can be streamed live on NBCOlympics.com and the NBC Sports app, as well as seen on the networks of NBCUniversal. The top two finishers in each event are guaranteed a spot in Tokyo, and the third and fourth-place finishers in certain events automatically qualify for the relay team. More relay participants could be added to the team later.
