Hillsboro Inlet Light, Maritime lighthouse in Hillsboro Beach, United States.

Hillsboro Inlet Light is a 132-foot (40 m) octagonal iron skeleton tower with a central stair cylinder, built in 1907. Its lower third is painted white and the upper two-thirds and lantern black; the open framework has four tapering legs with diagonal cross-bracing. The lantern room is topped by a black domed roof and finial, and a black gallery railing encircles it.

Congress approved construction of this navigation aid in 1901, and it began operating in 1907 with a kerosene lamp system. The tower served as a crucial guide for maritime traffic along the Atlantic coast.

Keepers' wives made sea grape jelly to trade with local farmers for pickled vegetables, and keepers used three 12 to 20 horsepower gas boats to assist shipwrecks. Four Coast Guard signalmen were barracked in a storehouse during World War I. The light was automated in 1974.

The lighthouse sits on a point that can be accessed from the nearby coastal road. Access may be limited depending on tidal conditions and weather, so check local conditions before visiting.

Inside the tower sits a second-order Fresnel lens imported from Paris, whose concentrated light rays historically sparked fires in the nearby Everglades. This optical component is a rare example of early 20th-century French lighthouse engineering.
