Dallas Crutcher Long (June 13, 1940 – November 10, 2024) was an American track and field athlete, who mostly competed in the shot put.

[3] He competed at the 1960 Summer Olympics, where he won a bronze medal behind fellow Americans Bill Nieder and Parry O'Brien.

One of his coaches was Frantisek (Frank) Louda, an American-Czech who had held the European hammer throw record in the 1930s.

Long returned four years later to Tokyo for the 1964 Summer Olympics and won a gold medal.

[4][5] Long's best mark in the shot put was a then-world record of 20.68 meters (67 ft 10 in) set at the U.S.-U.S.S.R. dual meet in 1964.
