Cecil Randolph Hundley Jr. is an American former professional baseball player and coach.

Hundley played the majority of his career with the Cubs and was considered their leader in the late 1960s and early 1970s. Despite being a light-hitter, Hundley was regarded as one of the best defensive catchers of his era, and the best Cubs catcher since Gabby Hartnett in 1940.
