The 1984 USA Outdoor Track and Field Championships took place between June 8–9 at Jaguar Stadium on the campus of San Jose City College in San Jose, California.
This meet was separate from the 1984 Olympic Trials, held in the Los Angeles Memorial Coliseum a week later.
Among the notable events at this meet were Leslie Maxie's youth world best in the 400 metres hurdles that lasted more than 30 years.
His hopes ended here when he was injured stepping into a crater left by a hammer during the preliminary round.
Local rivals John Powell and Mac Wilkins instead threw their season bests at this meet before going on to the silver (Wilkins) and bronze (Powell) medals at the Olympics in Los Angeles.
