1964 USA Outdoor Track and Field Championships

The 1964 USA Outdoor Track and Field Championships men's competition took place between June 26–28 at Rutgers Stadium in New Brunswick, New Jersey. The women's division held their championships separately at the new Hanford Bowl in Hanford, California. The Hanford Bowl was one of the first stadiums to sport an all-weather track made of asphalt and rubber. While this meet was separate from the Olympic Trials, since 1964 was an Olympic year, events were held over metric distances.

The Marathon championships were run in October at the Yonkers Marathon.
