List of United States records in masters athletics

These are the current records in the various age groups of masters athletics for United States competitors. Starting at age 35, each age group starts on the athlete's birthday in years that are evenly divisible by 5 and extends until the next such occurrence. For record purposes, older athletes are not included in younger age groups, except in the case of relay team members. A relay team's age group is determined by the age of the youngest member. There are two categories of relay records, one for composite teams made up of four American runners usually National teams at major championships, and a Club record for members of the same club, from the same Association.

Some masters events (hurdles, throwing implements) have modified specifications. The combined events use an age-graded result applied against the standard scoring table.

Based on IAAF rule 260.18a, since 2000, indoor marks superior to the outdoor record are eligible for record purposes. They are noted with an "i"
