Thomas Anthony Parsons (born September 13, 1939) is an American former Major League Baseball pitcher who played for the Pittsburgh Pirates (1963) and New York Mets (1964–65).

The native of Lakeville, Connecticut, was listed as 6 feet 7 inches (2.01 m) tall and 210 pounds (95 kg).

After he signed with Pittsburgh, the right-hander spent seven full years in their farm system, but he would make only one appearance in a Pirate uniform, as the starting pitcher in an 8–0 defeat in his debut against the Milwaukee Braves on September 5, 1963.

Parsons began the 1964 season pitching at Triple-A Columbus, then was traded by Pittsburgh to the Houston Colt .45s in June.

After he got into 19 games for Houston's Triple-A affiliate, the Oklahoma City 89ers, the June trade was cancelled and Parsons returned to the Pirates, who in turn sold his contract to the Mets.
