Ship Shoal Light, Screw-pile lighthouse in the Gulf of Mexico, Terrebonne Parish, Louisiana, US

Ship Shoal Light is a maritime lighthouse on the Gulf of Mexico featuring a 125-foot (38 meter) skeletal tower with a circular keeper's house at its base. The structure stands roughly 20 miles (32 kilometers) offshore and served to guide vessels through this navigation area.

Operations began in 1859 after this structure replaced a lightship called Pleasonton that had marked the area with red signals since December 1849. The main navigational light ceased operation in 1965 as shipping technology evolved.

The light's name comes from Ship Shoal, a bar called Ship Island Shoal on early maps. The tower is listed on Louisiana's register of historic places, and by the 2020s it was called the most endangered lighthouse on that register. The town of Berwick has been trying to save it by moving it to a park beside the already relocated Southwest Reef Light.

The tower stands abandoned in open gulf water about 20 miles (32 km) southwest of the Isles Dernieres, so there is no dock, landing or public access; it cannot be visited. The town of Berwick has been working to relocate the structure to a park beside the already-moved Southwest Reef Light, so check with Berwick before planning any trip.

Early lighthouse keepers suffered health problems linked to lead contamination in the water tanks used for drinking and washing. Authorities responded by removing the toxic red lead paint from the cisterns and coating them with coal tar to protect workers.
