100 Light Street (colloquially known by its most recent former label, the Transamerica Tower) is a 40-story, 528 ft (161 m) skyscraper completed in 1973 in downtown Baltimore, Maryland. It occupies the city block bounded by South Charles (Maryland Route 139), East Lombard, Light and East Pratt Streets. It is the tallest building in Baltimore and in Maryland.

Originally built as the USF&G Building, it is the headquarters of the United States Fidelity and Guarantee Company (USF&G) in Baltimore, Maryland. USF&G, a specialized insurance company founded in Baltimore in 1896, relocated here from its former complex of three adjoining early 20th Century masonry structures at the southwest corner of South Calvert and Redwood (formerly German Street before World War I) Streets. Later occupied by and known as the Legg-Mason Building, the structure faces the former "The Basin" of the Helen Delich Bentley Port of Baltimore on the Northwest Branch of the Patapsco River and the Inner Harbor downtown business waterfront redevelopment.
