South Palm Beach is a town in Palm Beach County, Florida, occupying a narrow stretch of the barrier island between the Town of Palm Beach to the north and the Town of Lantana to the south. With a population of 1,471 at the 2020 census, it is one of the smaller municipalities in the county, but its oceanfront position gives it a distinct and highly concentrated residential character. The town's geography is unusually simple. South Palm Beach is approximately five-eighths of a mile long, running along South Ocean Boulevard, which doubles as Florida State Road A1A and is essentially the town's only street. To the east lies the Atlantic Ocean, and to the west lies the Intracoastal Waterway, so the entire community is sandwiched between two bodies of water on a single narrow roadway. Because of its compact footprint, South Palm Beach developed almost entirely as a condominium and townhome community rather than a spread of single-family homes. Multi-story residential buildings line A1A, many offering ocean and waterway views, pools, and direct beach access. A notable portion of the community is oriented toward 55-and-over residents, giving the town a retiree and seasonal character alongside its year-round population. Life in South Palm Beach is quiet, walkable, and beach-centered. Residents are steps from the sand and within a short distance of Lantana's public beach park, Palm Beach's shops and dining, and the broader amenities of coastal Palm Beach County. For those seeking a compact, waterfront, low-maintenance home base on the barrier island, South Palm Beach offers a singular, small-town coastal setting.
