John F. McMullin was an American professional baseball player. During the first professional league season in 1871, he was the only regular left-handed pitcher, while in later seasons he mainly played the outfield. After playing almost every game throughout the five National Association seasons (1871–1875), he did not play a single game in the National League that succeeded it. He died in his native Philadelphia five years later, only 32 years old.
