John Francis Ferry (April 7, 1887 – August 29, 1954) was a pitcher and occasional pinch hitter in Major League Baseball.

[2] In mid-August of 1910, the defending World Series champion Pittsburgh Pirates purchased Ferry's contract from Jersey City.

[2] He made his major league debut on September 4, 1910, in relief of starter Howie Camnitz in the fifth inning of the game against the Cincinnati Reds.

[2] In 1912, Ferry was poised to become a crucial part of the Pirates pitching rotation, however, he only made 11 appearances the entire season.

Returning for the 1913 season, Ferry was described by Pirates executive Barney Dreyfuss as having "a better curved ball than any other pitcher" in the National League.
