Richard Lee Kenworthy (April 1, 1941 – April 22, 2010) was a third baseman in Major League Baseball who played for the Chicago White Sox (1962, 1964–1968). Listed at 5' 9", 170 lb., Kenworthy batted and threw right-handed. He was born in Red Oak, Iowa, United States.

Kenworthy was signed by the White Sox in 1961 out of the University of Missouri. He was assigned immediately to Class-A Clinton C-Sox, where he hit 22 home runs, a season team-record since then. Although Kenworthy finally caught on in the majors, he had to endure five more failed tryouts with Chicago, serving as a backup for Don Buford and Pete Ward.

In a six-season career, Kenworthy was a .215 hitter (54-for-251) with four home runs and 13 RBI in 125 games, including 12 runs, six doubles and one triple.

Kenworthy died in Kansas City, Missouri at the age of 69.
