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. The island is an important archaeological site due to its occupation during the Mesolithic period. Many archaeological finds have been made dating back to over 6,700 years before the present day, including the remains of over 20 people. 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.

The Mesolithic or Middle Stone Age is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the final period of hunter-gatherer cultures in Europe and the Middle East, between the end of the Last Glacial Maximum and the Neolithic Revolution. In Europe it spans roughly 15,000 to 5,000 BP; in the Middle East roughly 20,000 to 10,000 BP. The term is less used of areas farther east, and not at all beyond Eurasia and North Africa.
