Malvin Greston "Mal" Whitfield (born October 11, 1924) is a former American athlete, a double winner of 800 m at the Olympic Games.

Born in Bay City, Texas, Mal Whitfield, or Marvelous Mal as he was called, joined the United States Air Force in 1943. After World War II, he remained in the air force but also enrolled at Ohio State University. In the early 1950s he also served in the air force during the Korean War.

At the 1948 Olympics in London, Whitfield won the 800 m and was a member of the winning 4 × 400 m relay team. He also earned a bronze medal in the 400 m.

He won the NCAA title in the 800 m in 1948 and 880 yd in 1949 and the AAU title from 1949 to 1951 at 800 m, in 1953 and 1954 at 880 yd and in 1952 at 400 m.
