Mine Head Lighthouse, Lighthouse in Old Parish, County Waterford, Ireland

Mine Head Lighthouse is a cylindrical red sandstone tower painted white with a black horizontal band at mid-height, standing on steep cliffs above the Celtic Sea in Old Parish, County Waterford. It was built in 1851 and rises 22 m (72 ft). Two keeper's houses stand nearby, and a stone wall encloses the grounds.

The lighthouse was designed by George Halpin Senior in 1851 to guide vessels crossing the Celtic Sea. It was established to meet the growing navigation needs of maritime traffic in this coastal region.

The name Mionn Ard comes from the Irish for the headland, and the light is run by the Commissioners of Irish Lights from Dún Laoghaire. Two keeper's houses were built beside the tower and the grounds are enclosed by a stone wall. The site is open, but the tower itself is closed to visitors.

The location sits on steep cliffs with direct sea views, so sturdy footwear and care are needed when visiting. The best access comes via coastal paths in the surrounding area, which are easily walkable in good weather conditions.

Mine Head's light sits 87 m above sea level, the highest focal plane of any lighthouse in Ireland. The Commissioners of Irish Lights made the station fully automated in 1973, and a later switch to solar power cut the light's range to 32 km. It now shows four quick white flashes every 20 seconds.
