Derby Lane Greyhound Track is a racino located in St. Petersburg, Florida, United States. Originally named the St. Petersburg Kennel Club, it is the oldest continuously operating greyhound track in the country.
T.L. Weaver, a lumber entrepreneur, sold the tract of land Derby Lane is sited on to a group of local businessmen, who constructed the track and held its grand inaugural race on January 3, 1925. Shortly thereafter, however, the investors ran into financial hardship and were no longer able to make payments on the land. Possession of the track reverted to Weaver's lumber company, and Weaver decided to keep it and operate it himself. Derby Lane was still owned by the Weaver family as of November 2012.
