List of United States records in swimming
From Wikipedia, the free encyclopedia
There are two different kinds of swimming records in the United States and certified by USA Swimming:
- American record: the fastest time by an American swimmer.[1]
- U.S. Open record: the fastest time within the United States.[1]
Note: The American records should not be confused with the Americas records, which are the fastest times ever swum by a swimmer representing any country of the Americas.

Notes
- ^ Ilya Kharun initially represented Canada before announcing in January 2026 his intention to switch sporting citizenship to the US. Under World Aquatics rules, athletes must cease representing their former nation for 12 months before they can represent their new nation; Kharun becomes eligible to represent the US in October 2026. The attributed nation (or lack thereof) indicates which team he represented at the time.
