Cockspur Island Light, Historic lighthouse at Cockspur Island, Georgia, United States

Cockspur Island Light is a conical brick lighthouse in Georgia, about 46 feet (14 m) tall, built on wooden pilings that sit directly on an oyster bed in the Savannah River. The base of the tower is shaped like a ship's prow, allowing river currents to flow around it without damaging the structure.

The lighthouse was built in the late 1830s to guide ships along the Savannah River and remained active until 1909. It survived the Civil War battles that took place nearby at Fort Pulaski, even though the surrounding area was heavily fought over.

The name Cockspur comes from Cockspur Island, where the lighthouse stands on an islet in the south channel of the Savannah River. Since 2005, a 0.8-mile trail from Fort Pulaski National Monument leads visitors through brush to a vantage point; at low tide hikers can get within about 200 yards of the tower. The lighthouse is not open to the public, but kayakers often approach the water near the beacon, sometimes on commercial tours.

The lighthouse can be seen from the shore near Fort Pulaski National Monument, where a walking trail leads to good viewing spots along the river. Access to the island itself is limited by tides and is usually only possible on guided tours, so checking conditions before you go is a good idea.

The tower was built on an oyster and mussel bed, and its base is shaped like a ship's prow so waves and currents pass around it. During the Civil War bombardment of Fort Pulaski the lighthouse stood in the direct line of fire yet suffered little or no damage. It was relit on 18 March 2007 at 7:30 p.m. in a ceremony held by the National Park Service and the U.S. Coast Guard.
