Hornby Lighthouse, also known as South Head Lower Light, is an active lighthouse located on the tip of South Head, New South Wales, Australia, a headland to the north of the suburb Watsons Bay. It marks the southern entrance to Port Jackson and Sydney Harbour, as well as lighting the South Reef, a ledge of submerged rocks. It is the third oldest lighthouse in New South Wales.

The need for a lighthouse at the entrance of Jackson Bay was made evident by the loss of two ships. First was the Dunbar, wrecked in August 1857, with the loss of 121 lives. The second was Catherine Adamson, two months later in October 1857, with a loss of twenty-one lives.

A committee of the Light, Pilot and Navigation Board took evidence in September 1857 and recommended the construction of a 30 feet (9.1 m) lighthouse on the inner South Head, showing a fixed white light (F.W.), although a red light was also considered.

The lighthouse was designed by Alexander Dawson, the New South Wales Government Architect at that time. Dawson approved the recommended location as having adequate foundations, and also reported that the government stores already had a catoptric lens apparatus available that has been purchased in 1853.

The tower construction ended in 1858, and it was the third lighthouse built in New South Wales, following Macquarie Lighthouse in 1818 and Nobbys Head Light in 1858. It was opened by Sir William Denison, Governor of New South Wales, and named after the family of his wife Caroline, daughter of Admiral Sir Phipps Hornby, though it was known as the "Lower Light", to distinguish it from Macquarie Lighthouse, the "Upper Light".
