Wollongong Breakwater Lighthouse, Maritime lighthouse at Wollongong Harbour, Australia

Wollongong Breakwater Lighthouse is a steel structure built on a concrete base at the southern end of the harbor's protective barrier. The breakwater extends into the water, creating a sheltered area for vessels entering and leaving the port.

Wollongong Borough Council petitioned for a harbour light in 1866, and the tower was built in 1871 to guide coal-trade shipping into the port. Heavy seas delayed construction, and a temporary red light in a box at the pier's end served until the lantern was installed in July 1871; the light was not exhibited regularly until January 1872. Deactivated in 1974, it was restored by local effort and again in 2002.

The lighthouse marks the harbor's role in the region's connection to the sea and maritime trade. Today, visitors and locals use the breakwater as a place to walk, fish, and watch the water.

The lighthouse is reached by walking paths along the breakwater, which are generally flat and easy to navigate. Parking and information panels are located near the harbor entrance, and dry weather makes the visit more comfortable.

The 2000 local heritage listing calls it Australia's first prefabricated steel lighthouse, citing early achievements in prefabrication and in applying new technology to the building tasks of the era. It is one of only two towers in New South Wales made from wrought iron plates; the other, Warden Head Light, was built at Ulladulla Breakwater and later moved to Warden Head.
