Princess Amelia's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, adjacent to Gun No. 4 of Princess Anne's Battery. It was named after Princess Amelia of Great Britain, the second daughter of George II. It was formerly referred to as the 2nd Willis's Battery. The plateau and its batteries had previously been named after an artillery officer by the name of Willis who was outstanding during the capture of Gibraltar in 1704. Princess Amelia's Battery saw action during the Great Siege of Gibraltar, during which it sustained substantial damage. Little remains of the original site, aside from two derelict buildings. The battery is listed with the Gibraltar Heritage Trust.

Princess Amelia's Battery is in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. The artillery battery is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, above Princess Caroline's Battery and adjacent to the fourth gun of Princess Anne's Battery. Both Princess Amelia's Battery and the adjacent Gun No. 4 are on higher ground than that of Guns No. 1 through 3 of Princess Anne's Battery.

The site was initially known as the 2nd Willis's Battery. The Willis's Batteries were constructed at the area of the former Reduto (English: Redoubt) de San Joachim, at an elevation of 440 feet above the isthmus. During the capture of Gibraltar in 1704, an artillery officer by the name of Willis was outstanding in his manning of the guns. To honor the officer, the Batteries of San Joachim and the Bastion of San Jose were renamed Willis's. The site was renamed again after Princess Amelia (1711 – 1786), the second daughter of King George II. The proximity of the battery to Princess Anne's Battery is such that the latter is sometimes mistakenly referred to as Princess Amelia's Battery. Princess Amelia's Battery was one of several on Willis's Plateau that also included Princess Anne's Battery and Princess Royal's Battery.
