No, not "all" of the Lake Worth area is now Lake Worth Beach, but the city itself officially changed its name in 2019. The "City of Lake Worth Beach" took this action to distinguish the incorporated municipality from the large, unincorporated areas of Palm Beach County that were also using the name "Lake Worth" for mailing addresses. The name change applies to the city limits, including the downtown historic district and the municipal beach. The Lake Worth Lagoon (the body of water) and the unincorporated "Lake Worth" neighborhoods to the west remain unchanged in their formal designations. For travelers in 2026, using the full name "Lake Worth Beach" is the best way to ensure your GPS or rideshare takes you to the vibrant coastal downtown area rather than a suburban residential neighborhood several miles inland.
