city, seat (1909) of Palm Beach county, southeastern Florida, U.S. It is situated along the western shore of Lake Worth (part of the Intracoastal Waterway), a lagoon separated from the Atlantic Ocean to the east by a barrier island, about 65 miles (105 km) north of Miami. The town of Palm Beach lies opposite the city on the barrier island.

The area, homesteaded in 1880 by Irving R. Henry, a settler from North Carolina, was developed after the arrival in 1894 of Henry M. Flagler (Flagler, Henry M)'s Florida East Coast Railway. Using the town as a workers' base and transfer point, Flagler developed a winter resort across the lagoon at Palm Beach. As transport facilities improved (which, in addition to the railroad, included constructing the West Palm Beach Canal westward to Lake Okeechobee (Okeechobee, Lake)), West Palm Beach also became a tourist centre, as well as the commercial and financial hub of the area.

Tourism is still the basis of West Palm Beach's economy, and manufacturing (including jet and rocket engines), high-technology industries, and citrus shipping are also important. The area has a large retiree population. The Port of Palm Beach, one of the busiest ports in the state, is immediately to the north.

The city is the home of Palm Beach Atlantic College (1968). Cultural institutions include opera and ballet companies and an art museum. The South Florida Science Museum has a planetarium and aquarium. To the west is Lion Country Safari, a 500-acre (200-hectare) preserve where African animals roam freely amid surroundings similar to their native habitats. Loxahatchee National Wildlife Refuge, in the northern Everglades, is about 15 miles (25 km) southwest of the city. Inc. 1894. Pop.
