Téviec or Théviec is an island situated to the west of the isthmus of the peninsula of Quiberon, near Saint-Pierre-Quiberon in Brittany, France.

One of the most remarkable finds was that of the grave of two young women who had apparently died violently but had received an elaborate burial under a "roof" of antlers, their bodies decorated with jewellery made from shells.

[5] The island is one of only a few known Mesolithic sites in Brittany, along with Pointe de la Torche, Hoëdic and Beg er Vil on the Quiberon peninsula.

[1] During the Mesolithic period, the sea level was much lower – it was possible to walk from France to England – and Téviec was situated in a lagoon.

[6] The grave assemblage was excavated from the site in one piece and is now on display at the Muséum de Toulouse, where its restoration in 2010 earned a national award.
