The Tropical Hockey League (THL) was a short-lived ice hockey minor league in Miami, Florida. The initial league had four teams, all based in Miami, and lasted for only one season, 1938–39, before folding; it was briefly resurrected in 1940 before folding for good the following year. Nicknamed the Grapefruit League, it was notable as the first attempt to establish professional hockey in Florida—or the Southern United States in general—though it ultimately had minimal impact on popularizing the sport in the region.
