Warden Head Light, also known as Ulladulla Lighthouse, is an active lighthouse on Warden Head, a headland south of Ulladulla, New South Wales, Australia, guarding the entrance to the Port of Ulladulla. It is one of only two wrought iron lighthouses in New South Wales, the other being its sibling, Wollongong Breakwater Lighthouse. It is also notable for two relocations: the tower was constructed in 1873 on the Ulladulla Breakwater, and relocated in 1889 to its current location. Its keeper's house was relocated to a different location in the 1920s.

Ulladulla is a coastal town in New South Wales, Australia in the City of Shoalhaven local government area. It is on the Princes Highway about 230 kilometres (140 mi) south of Sydney, halfway between Batemans Bay to the south and Nowra to the north. Ulladulla has close links with the nearby historic settlement of Milton and many services are shared between these towns.
