Jupiter Island

Jupiter Island is a narrow barrier island stretching roughly 3.6 square miles (9.3 km²) along Florida's Atlantic shoreline. Residential areas sit between the Indian River to the west and the open coast to the east, surrounded by dunes and protected coastal forest.

The town incorporated in 1953, emerging as a separate municipality within Martin County. Before that time, the area belonged to larger administrative districts and served mainly as uninhabited coastal land.

The town follows strict building codes that require dense landscaping and setbacks from the shoreline. Visitors notice almost no storefronts or public signage along the roads, giving the settlement a private and secluded appearance.

Two bridges connect the island to the mainland, one at the north end and another near Hobe Sound to the south. Visitors find few public parking areas or access points, as nearly all of the land is privately owned residential property.

In 2020, only about 800 residents lived on the island, making it one of the least populated towns in Florida. Despite this small number, the community ranks among the wealthiest in the entire state.
