The Citrus Center, also known as the BB&T building, originally known as the CNA Tower, is a commercial office building in Orlando, Florida, United States located at 255 South Orange Avenue.

Topped out in December 1970 and completed in April 1971, it was the first modern skyscraper in Orlando.

The roof contains a large structure to house electrical power switching circuitry, seven elevator winches (six passenger and one freight) and window-washing equipment (a workers' cradle and davit) mounted on rails.

Originally it was decorated with large, dark-blue translucent letters spelling C N A along the four sides of its parapet top floor, which were illuminated at night in a light blue color; this was for years a feature of the Orlando skyline, visible for fifteen miles by road (and at least 50 miles from the Kennedy Space Center if from a high-enough vantage such as the VAB and 22 miles from the Citrus Tower in Clermont, it was also visible from the taller International Drive hotels and Lake Buena Vista and Disney World hotels.)

Two workers were killed in its construction, one of which was an iron-worker who fell to his death on the Orange Avenue side a month before the topping-out.
