Tuskar Rock (Irish: An Tuscar) is a group of rocks topped by a lighthouse 11 kilometres (6.8 miles) off the southeast coast of County Wexford, Ireland. It has probably destroyed more ships than any other Irish coastal feature. One hundred and seventy-six wrecks are listed for the Tuskar Rock area at Irish Wrecks Online.
It is mentioned in the Irish ballad Tales of Loch Achray as the place where the clipper Loch Achray dropped her tug, before sailing to the South Atlantic where she was wrecked off the River Plate.
The Tuskar Rock lighthouse, built from granite and standing 120 feet (37 metres) tall, was built over a period of years beginning in 1812. In October of that year, a storm struck, washing away temporary barracks that had been erected on the island, and killing fourteen workmen—the worst such disaster in Ireland's history of lighthouse construction. The surviving workers clung to the island's slippery rocks for two full days before being discovered and rescued. Work resumed, and the lighthouse was completed, entering into operation on 4 June 1815.
The Tuskar Rock air disaster occurred near the rock on 24 March 1968 when Aer Lingus flight 712, en route from Cork to London, crashed into the sea with the loss of all 61 people on board.
The name Tuskar rock has no foundation in the Irish language but actually came from the Vikings. It is one of many Viking place names found in the south of Wexford and means simply large (tu) rock (skar) in Old Norse.
