Palm Beach Gardens is a city in Palm Beach County in the U.S. state of Florida. The city is in the center of a rapidly-developing area north of West Palm Beach in the northern part of the county and the South Florida metropolitan area. As of the 2010 United States Census^[update], the population was 48,452. The city has a number of gated communities.

The city has a total area of 55.3 square miles (143 km²). 55.1 square miles (143 km²) of it is land and 0.2 square miles (0.52 km²) of it (0.45%) is water.

Prior to development, the land that became Palm Beach Gardens was primarily cattle ranches and pine forests, as well as swampland further west. In 1959, wealthy landowner and insurance magnate John D. MacArthur announced plans to develop 4,000 acres (16 km²) and build homes for 55,000 people. He chose the name Palm Beach Gardens after his initial choice, Palm Beach City, was denied by the Florida Legislature, because of the similarity of the name to the nearby Palm Beach. MacArthur planned to build a "garden city" so he altered the name slightly. The city was incorporated as a "paper town" (meaning that it existed only on paper) in 1959. The 1960 Census recorded that the city officially had a population of one, apparently a squatter whom MacArthur had allowed to stay on his property.

Florida (ⁱ/ˈflɒrɪdə/) is a state in the southeastern United States, bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia and to the east by the Atlantic Ocean. Florida is the 22nd most extensive, the 4th most populous, and the 8th most densely populated of the 50 United States. The state capital is Tallahassee, its largest city is Jacksonville, and the South Florida metropolitan area is the largest metropolitan area in the southeastern U.S.

Much of Florida is situated on a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Its geography is marked by a coastline, by the omnipresence of water and the threat of hurricanes. Florida has the longest coastline in the contiguous United States, encompassing approximately 1,350 miles (2,170 km), and is the only state to border both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and its terrain is characterized by sedimentary soils. The climate varies from subtropical in the north to tropical in the south. Its symbolic animals like the American alligator, Florida panther and the manatee, can be found in the Everglades, one of the most famous national parks in the world.
