Punta Delgada Lighthouse, Maritime lighthouse at Valdes Peninsula, Argentina

Punta Delgada Lighthouse is a 14-meter circular cast-iron tower with a gallery and lantern, painted red with a black lantern. It stands in the southeast of the Valdés Peninsula, in Biedma Department, Chubut Province, Argentina, and is managed by the Servicio de Hidrografía Naval. It emits three white flashes (2+1) every 25 seconds from a focal height of 71 meters, with a range of 28 nautical miles (about 52 km).

The lighthouse began operations on May 1, 1905, serving as a critical navigation point for vessels traveling the Patagonian coast. Its establishment was part of Argentina's effort to improve maritime safety in this remote coastal region.

The lighthouse has been a national historic monument since 15 November 2010. Its annex buildings now serve as a hotel and restaurant, and the tower is still staffed, so the site is lived in rather than abandoned. The name Punta Delgada, "thin point", refers to the narrow tip of the Valdés Peninsula where it stands.

The lighthouse stands 70 km from Puerto Pirámides, in the southeast of Península Valdés, and is reached by road across the peninsula. The tower is staffed and its annex buildings serve as a hotel and restaurant, so a stay can be arranged on site. The light is produced by an autonomous electric generator.
