The 2002 USA Outdoor Track and Field Championships was organised by USA Track & Field and held from June 21 to 23 at the Cobb Track & Angell Field in Palo Alto, California. The three-day competition served as the national championships in track and field for the United States. The same facility would host this meet the following year, but this was the last year to use the three day format as the four-day format was adopted in 2003. The combined track and field events were contested at Edwards Stadium in Berkeley, California in the two days preceding the start of the main programme.
Marion Jones won a women's 100 m/200 m sprint double – the third time in her career that she had done so, and her fifth straight 200 m win. Four had their fourth consecutive title at the event: Regina Jacobs in the 1500 m, Gail Devers in the 100 m hurdles, Sandra Glover in the 400 m hurdles, and Stacy Dragila in the pole vault. On the men's side Allen Johnson had his third straight and fifth career 110 m hurdles win. In the throws both Breaux Greer (javelin) and Adam Setliff (discus) took their third consecutive titles, while Lance Deal won his ninth career (and final) hammer throw championship.
The sprinting events were affected by retrospective doping disqualifications: the original men's 200 m and 400 m winners Ramon Clay and Alvin Harrison were stripped of their national titles. Darvis Patton and Angelo Taylor were raised to the status of national champion as a result. Men's 100 m runner-up Tim Montgomery was also disqualified, as was women's 100 m third-placer Kelli White.
The competition was used to select the national teams to be sent to the 2002 IAAF World Cup and also the 2002 IAAF World Race Walking Cup. Four American national champions went on to win at that year's IAAF World Cup competition: James Carter (400 m hurdles), Savanté Stringfellow (long jump) Adam Nelson (shot put) and Gail Devers (100 m hurdles).
