John Day Gleason (July 14, 1854 – September 4, 1944) was a 19th-century professional baseball player who primarily played third base. His younger brother, Bill Gleason, was also a ballplayer.

Gleason appeared in one game for the St. Louis Brown Stockings of the National League in 1877, that team's last season.{{Cite web |last=admin |title=Jack Gleason – Society for American Baseball Research |url=https://sabr.org/bioproj/person/jack-gleason/ |access-date=2024-06-18 |language=en-US}} He then played in the American Association for the St. Louis Browns in 1882 and the beginning of 1883, and the Louisville Eclipse for most of 1883. From 1884 to 1885, Gleason played for the St. Louis Maroons during their only Union Association season and first in the National League. He played his last season in 1886 for the Philadelphia Athletics in the American Association. He later managed the San Francisco club in the Pacific Coast League in 1906, 1907 and 1909.

He was the last living player from the 1877 season at his death.
