Nun's Well is an ancient underground water reservoir in the British Overseas Territory of Gibraltar. It is located at Europa Point, and is thought to be of the Moorish period. It represents some of the earliest evidence of an artificial water supply in Gibraltar. The name of the cistern is thought to be derived from the nuns associated with the Shrine of Our Lady of Europe. In the eighteenth century, Nun's Well supplied the military with water. In the early nineteenth century, it provided water for the brewery that was built next door. In 1988, the Royal Engineers constructed what is now the main building, which has a castle-like appearance. Nun's Well became the focus of controversy during the 2010-2011 restoration of the site.

Nun's Well is an ancient subterranean water reservoir in Gibraltar, the British Overseas Territory at the southern end of the Iberian Peninsula. It is located at Europa Point, the southernmost portion of Gibraltar. The cistern is on Europa New Road at Europa Flats, across from the south entrance to Keightley Way Tunnel, just south of the Ibrahim-al-Ibrahim Mosque. On the east side of the structure, the reservoir is accessed by stairs which lead to a door constructed at the underground level. The water reservoir includes a pair of large underground arched chambers into which ground water was permitted to drain. Nun's Well is thought to be of the Moorish period, and represents some of the earliest evidence of the attempts to provide a water supply in Gibraltar.

It is thought that the name of the cistern originated with the nuns who previously cared for the Shrine of Our Lady of Europe, another historic site at Europa Point. Nun's Well is also in proximity to the Europa Point Lighthouse.
