Wollongong Breakwater Lighthouse, also known as Wollongong Harbour Lighthouse, is a historic lighthouse situated on the southern breakwater of Wollongong Harbour, in Wollongong, a coastal city south of Sydney, New South Wales. Wollongong is the only place in the east of Australia to have two lighthouses located in close proximity of each other, the other being Wollongong Head Lighthouse. While no longer used, the lighthouse was restored in 2002 as operational and is listed an official heritage building.
The Wollongong Harbour is home to private vessels and the local fishing fleet in the inner Belmore Basin. South of the city lies Port Kembla, a major steelmaking, minerals, grain and vehicle handling harbour. A further hazard to shipping is an island group known collectively as The Five Islands lying a short distance off the coast.
