Lake Worth Beach, previously named Lake Worth, is a city in east-central Palm Beach County, Florida, United States, located about 63 miles (101 km) north of Miami. The city’s name is derived from the body of water along its eastern border known as the Lake Worth Lagoon, which was named for General William J. Worth, who led United States Army forces during the last part of the Second Seminole War. Lake Worth Beach is situated south of West Palm Beach, southeast of Lake Clarke Shores, east of Palm Springs, and north of Lantana, while a small section of the city also partitions the town of Palm Beach.
