Hœdic or Hoëdic (French pronunciation: [edik];[3][4] Breton: Edig) is an island off the south coast of Brittany in northwestern France.

[5] Hœdic is located in the heart of Mor Braz [fr], a bay in the Atlantic Ocean off the south coast of Brittany (Rhuys and Quiberon peninsulas), 13 km (8.1 miles) east of Belle-Île and 5 km (3.1 miles) southeast of Houat.

It is part of a line of granite crests that includes the Le Croisic peninsula, Dumet Island, Houat, Quiberon, and Groix.

Its peak, at an altitude of 22 metres (72 ft), is located in the middle of its eastern part, on the road that leads from the village to the hamlet of the Phare.

During the summer, its population can reach 3,000, including boaters, tourists, and campers coming to the island.
