The Jupiter Inlet is a natural opening through the barrier islands of Martin and Palm Beach counties in Jupiter, Florida, that connects the south end of the Indian River Lagoon and the Loxahatchee River to the Atlantic Ocean.
It is one of the six primary inlets that provide exchange between the Indian River Lagoon System—a brackish estuarine complex extending along Florida’s east coast—and oceanic waters. The inlet allows tidal flow to regulate salinity levels in nearby estuaries, supports nutrient exchange, and provides a navigable waterway for marine vessels traveling between inland waters and the open sea.
