Donald Ray Elston (April 6, 1929 – January 2, 1995) was an American relief pitcher who appeared in 450 games in Major League Baseball, all but one of them as a member of the Chicago Cubs (1953, 1957–1964).

A hard thrower, Elston played for perennially weak Cubs teams over the course of his nine-year major league tenure.

After a brief late-season trial with the 1953 Cubs, when he was treated rudely by the Philadelphia Phillies and St. Louis Cardinals,[1] he was sent back to the minor leagues for the next two campaigns.

Chicago included him in a December 1955 trade with the defending world champion Brooklyn Dodgers that was headlined by veterans Randy Jackson, Don Hoak, Russ Meyer and Walt Moryn, but Elston remained in the minors for all of 1956.

He came on in the ninth inning of the first of 1959's two All-Star tilts and earned a save to preserve a 5–4 victory over the American League at Forbes Field, Pittsburgh, on July 7.
