Mew Island Lighthouse is an active lighthouse within the Copeland Islands of County Down in Northern Ireland. The current 19th-century tower is the most recent in a series of lighthouses that have been built in the islands, which have helped to guide shipping around the archipelago and into Belfast Lough.

A number of different fuels, including coal gas, paraffin, and diesel, have been used to power the lighthouse. In 2015, the Commissioners of Irish Lights, who operate the lighthouse, replaced the hyperradiant Fresnel lens optic with a flashing LED system that uses only solar power. This large optic was then preserved and is now on display in the Titanic Quarter of Belfast as a visitor attraction known as The Great Light.^[1]^[2]^[3]
