The USA Olympic swimming team has been decided, and there is no shortage of big names on the roster.
Caeleb Dressel, Bobby Finke, Chase Kalisz, and Ryan Murphy are the past Olympic gold medalists on the men's side who lead a group of swimmers featuring plenty of young stars ready to make their mark on the global stage.
Of course, there are some marquis names on the women's side. Katie Ledecky is back to compete in a wave of events, as are other standouts like Lilly King, Regan Smith, Simone Manuel, and the Walsh sisters.
The 2024 Paris Olympics is shaping up to be a thrilling battle between the Americans and Australians, two nations that battled it out in a close finish back in the 2021 Tokyo Games, with the United States ultimately taking the victory in both gold and total medals.
Here is a look at all the 2024 U.S. men's and women's Olympics swimmers.
