Palm Beach is an incorporated town in Palm Beach County, Florida, United States. Located on an island in east-central Palm Beach County, the town is separated from several nearby cities including West Palm Beach and Lake Worth Beach by the Intracoastal Waterway to its west, though Palm Beach borders a small section of the latter and South Palm Beach at its southern boundaries. As of 2010 census, Palm Beach had a year-round population of 8,348 and an estimated population of 8,816 in 2019, increasing by around 25,000 people between November and April.
Settlers began arriving in modern-day Palm Beach as early as 1872, and opened a post office about five years later. Elisha Newton "Cap" Dimick, later the town's first mayor, established Palm Beach's first hotel, the Cocoanut Grove House, in 1880, but Standard Oil tycoon Henry Flagler became instrumental in transforming the island of jungles and swamps into a winter resort for the wealthy.
