John Thomas Winsett (November 24, 1909 – July 20, 1987) was an American professional baseball player.

Nicknamed "Long Tom", he played all or part of seven seasons in Major League Baseball for the Boston Red Sox (1930–31, 1933), St. Louis Cardinals (1935) and Brooklyn Dodgers (1936–38), primarily as a left fielder.

In 1936, Winsett hit 50 home runs for the minor league Columbus Red Birds.

On April 25, 1938, he was the first baseball player to be featured on the cover of LIFE magazine,[citation needed] with an inside caption which read: "The rubber-legged batter on the cover is John Thomas Winsett, of McKenzie, Tenn. one of the most curious players on the most curious team in the major leagues.

First time Winsett batted in a big-league game he hit a homer, but shortly went back to the minors.
