The Henry Head Battery is an artillery battery on the northern side of the entrance to Botany Bay at Henry Head, La Perouse, New South Wales Australia.

[1] Constructed between 1892 - 1895 with 2 BL 6-inch Mk V disappearing guns,[2] the fort operated until 1910, after which it became obsolete.

The battery, along with two six-inch (152.4 mm – diameter) gun emplacements and observation posts, was re-employed during World War II to defend the approaches to Botany Bay.

[2] The underground bunker and tunnel complex consisted of vaulted ammunition storage rooms with double walls and ceilings, which were designed to stop them collapsing in the event of a direct hit.
