List of United States records in swimming

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.

An asterisk (*) indicates that this record has been achieved since the latest USA Swimming records publication. A plus (+) indicates that this record also is the current world record.
