Point Lynas Lighthouse (Welsh: Goleudy Trwyn y Balog) is located on a headland in Llaneilian Community, on the north-east corner of Anglesey in North Wales (at grid reference SH479936).

Whilst the light is retained in operational use, the building and associated lighthouse keepers cottages were returned to the Mersey Docks and Harbour Board who sold them to be a private home and holiday accommodation.

Point Lynas was first lit in 1779 at a site about 300 metres (980 ft) south of the present tower, to provide accommodation for Liverpool pilots making use of the shelter at Porthyrysgaw.

The unusual arrangement of having the lantern at ground level with the look-out and telegraph room above is similar to the Great Orme Lighthouse, also built by the Mersey Docks and Harbour Board.

The fixed part of the optic consists of three sections, the central unit on the focal plane has a 0.25 metres (9.8 in) deep curved lens with bands of six prisms above and below it.
