James Robert Campbell (born June 24, 1937) is an American former professional baseball player, a catcher who played 82 games in the Major Leagues for the Houston Colt .45s during 1962 and 1963.

He'd signed originally with the Pittsburgh Pirates in 1955, was briefly loaned to the Chicago White Sox organization, and played for six seasons without reaching the Double-A level.

After the 1960 minor-league season, he was drafted by the Milwaukee Braves, then traded on February 23, 1961, to the newborn Colt .45s,[1] founded as a National League expansion team set to debut in 1962.

To prepare for their first MLB season, the Colt .45s — known as the Astros since 1965 — were acquiring minor league players to stock their organization and loaning them to other teams' minor-league clubs.

Campbell was the Buffs' first-string catcher in 1961[2] and then was assigned to the Colt .45s' top 1962 affiliate, the Oklahoma City 89ers of the American Association.
