Charles Henry Weeghman (March 8, 1874 – November 1, 1938) was a German American restaurant entrepreneur and sports executive. Beginning in 1901, he began opening quick-service lunch counters throughout downtown Chicago. After failing to acquire the St. Louis Cardinals baseball club in 1911, he became one of the founders of the upstart Federal League in 1913 as the owner of the Chicago Whales.
