East Weare Battery is a derelict Victorian gun battery on the Isle of Portland in Dorset, England. It is located within the East Weares area of the island, overlooking Portland Harbour which it was built to protect, and sits below the cliff to the east of the Verne Citadel. The battery has sections from A to F, with the overall condition varying from poor to good. In May 1993 the site became Grade II Listed.
