Jack Pfefer (also commonly spelled as "Pfeffer"; December 10, 1894 – September 13, 1974) was an American professional wrestling promoter during the early-to-mid twentieth century. He pioneered an earlier form of sports entertainment, as he was one of the first promoters to visualize the pro wrestling business in the mold of theater. However, he developed an infamous reputation when he exposed the sport's inner secrets to the mainstream press in a spiteful attack that nearly destroyed the entire industry.
