James Robert Qualls (born October 9, 1946) is an American former professional baseball player who appeared in 63 games in Major League Baseball as an outfielder and pinch-hitting specialist for the Chicago Cubs (1969), Montreal Expos (1970) and Chicago White Sox (1972).

Born in Exeter, California, he was a switch-hitter who threw right-handed; he stood 5 feet 10 inches (1.78 m) tall and weighed 158 pounds (72 kg).

Qualls began his pro career in the Cubs' organization in 1964 after graduating from Tulare Western High School.

After five years in the minor leagues, he made the MLB roster in 1969 and played 43 games for the Cubs, most of them in utility and pinch-hitting roles.

He is best remembered for hitting a one-out single in the top of the ninth inning to break up Tom Seaver's bid for a perfect game in the New York Mets' 4–0 victory over the Cubs at Shea Stadium on July 9, 1969.
