Singer Island is a peninsula on the Atlantic coast of Palm Beach County, Florida, in the South Florida metropolitan area. Most of it is in the city of Riviera Beach, but the town of Palm Beach Shores occupies its southern tip. Its latitude of is 26.784 N and its longitude is −80.037; Florida's easternmost point is in Palm Beach Shores. Before the Palm Beach Inlet was created, Singer Island was connected to the island of Palm Beach to the south.
Named after Palm Beach developer Paris Singer, a son of the Singer Sewing Machine magnate Isaac Singer, Singer Island has parks, marinas, hiking and bike paths, as well as 4.7 miles (7.6 km) of white sand beach that has been considered one of the top five beaches in Palm Beach County.
Singer Island is 3 miles (4.8 km) from North Palm Beach, 5.4 miles (8.7 km) from West Palm Beach, 5.4 miles (8.7 km) from Palm Beach Gardens, 6.2 miles (10.0 km) from Juno Beach, and 10.6 miles (17.1 km) from Jupiter.
Singer Island was originally planned by Paris Singer as a development called Palm Beach Ocean. Along with Addison Mizner, Singer intended to build a luxury resort hotel called the Paris Singer Hotel on the south end of the island, and a more typical resort called the Blue Heron toward the north, with homes and a golf course in between. Due to problems clearing titles, Singer's plans changed, and he decided to build only the luxury hotel on the island's south end and to call it the Blue Heron. Virtually every home lot in Palm Beach Ocean was sold, and $2 million (the equivalent of approximately $28 million in 2018) was poured into the Blue Heron. However, due to the abrupt end of the Florida land boom of the 1920s, not a single house was built on any of lots, and the Blue Heron was left uncompleted.
