O'Hara's Battery is in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. The artillery battery is located near the southern end of the Upper Rock Nature Reserve, near Lord Airey's Battery, at the highest point of the Rock of Gibraltar, . The emplacement is in the Upper Battery area, which also includes Lord Airey's Battery and Spur Battery, although the gun of the latter was removed in Project Vitello. It is positioned at the southern terminus of O'Hara's Road, known as O'Hara's Point. The battery and road were named after the Governor of Gibraltar General Charles O'Hara (1740-1802). He served as governor from 1795 until his death in February 1802. O'Hara was replaced as governor later that year by Prince Edward, the Duke of Kent, and future father of Queen Victoria.
