city, seat (1856) of Orange county, central Florida, U.S. It is situated in a region dotted by lakes, about 60 miles (95 km) northwest of Melbourne and 85 miles (135 km) northeast of Tampa. The city is the focus for one of the state's most populous metropolitan areas.

The region was originally inhabited by Timucua and later Seminole peoples. Settlement began about 1843 around Fort Gatlin, a U.S. Army post. First called Jernigan for Aaron Jernigan, an early settler, the town was renamed in 1857 to honour Orlando Reeves, an army sentry killed during the Seminole Wars. Prior to the American Civil War, the area was a cotton and cattle centre; after the war, citrus became a leading industry. The South Florida Railroad arrived in 1880 and was extended to Tampa in 1883. The development after 1950 of the Cape Canaveral (Canaveral, Cape) aerospace complex, 50 miles (80 km) east, spurred population and economic growth, which were further boosted when Walt Disney World (Walt Disney World Resort) opened in 1971 about 20 miles (30 km) southwest. The construction of other attractions followed, and the city acquired a National Basketball Association franchise (the Orlando Magic) in 1987.

The Disney complex alone covers 47 square miles (122 square km). In addition to its several large resorts, Walt Disney World has a variety of attractions, including the Magic Kingdom, Epcot, Disney-MGM Studios, and Animal Kingdom. Also in the greater Orlando area are Universal Orlando (with the Universal Studios and Islands of Adventure theme parks), Sea World of Florida (a marine-animal park), and Wet 'n Wild (a large water park). Lack Haven Park contains art, science, and history museums. Gatorland, just to the south, is home to alligators and crocodiles.

Tourism, conventions, and trade shows are the basis of the city's economy. Manufacturing (especially of aerospace and missile systems), high-technology industries, and the citrus industry are also important. Educational facilities include the University of Central Florida (Central Florida, University of) (1963) and Valencia Community College (1967). Inc. 1875. Pop.
