Gorman Thomas is a former professional baseball player. In 1971, Thomas played Class A baseball in the Milwaukee system, with the Danville Warriors that year, Thomas led the Midwest League in both home runs and strikeouts. The next year with the Class AA San Antonio Brewers, Thomas led the Texas League in the same two categories, registering 26 home runs versus 171 strikeouts.

Thomas spent parts of 1973 and 1974 in the major leagues with the Brewers, but he mostly played Class AAA baseball during those seasons. He played Major League Baseball as a center fielder and right-handed hitter. Thomas played in the AL with the Milwaukee Brewers, Cleveland Indians and Seattle Mariners. With the Brewers, Thomas was one of the franchise's most popular players. He was a leading home run hitter in the late 1970s and early 1980s, though he hit for a low batting average and frequently struck out. Thomas had good fielding skills and his throwing arm was strong until shoulder surgery in 1984, after which he became a designated hitter until his retirement in 1986. 

Since 2015 Thomas has marketed "Stormin' Gorman's B.B.Q. Sauce", a mustard based condiment that can be enjoyed with various meats and vegetables. It is available at American Family Field, home ballpark of the Milwaukee Brewers, as well as retail establishments in Wisconsin.
