Ta' Għemmuna Battery (Maltese: Batterija ta' Għemmuna) was an artillery battery in St. Julian's, Malta, that was built by Maltese insurgents during the French blockade of 1798–1800.
The battery was located at Dragonara Point, in front of the Hospitaller entrenchments at Spinola.
The battery was built by Vincenzo Borg in February 1799, after a French force of around 30 ships was sighted close to the Maltese coast.
The battery was built to prevent a French relief force from landing at St. Julian's Bay and St. George's Bay, therefore protecting other insurgent positions from the rear.
A rough sketch of the battery by Sammut still exists and was retrieved by the architect Andre Zammit.
