Bradley's Head is a headland protruding from the north shore of Sydney Harbour, within the metropolitan area of Sydney, New South Wales, Australia.

The foremast of the cruiser HMAS Sydney, renowned for taking part in the Royal Australian Navy's first ship against ship engagement in World War I, is mounted on the headland as a memorial to that battle. In June 2000, the mast was rededicated as a monument to all Australian ships and sailors lost in conflict.
