Goeree-Overflakkee (Dutch pronunciation: [ɣuˌreː ˈoːvərflɑˌkeː]) is a delta island and an administrative municipality in the province of South Holland, Netherlands, with a population of 50,589. It is the largest island by land area in the Netherlands after the man-made Flevopolder.

Goeree-Overflakkee is separated from the islands of Voorne-Putten and Hoeksche Waard by the Haringvliet, from the mainland of North Brabant by the Volkerak, and from Schouwen-Duiveland by Lake Grevelingen.

Despite being part of the province of South Holland, the island's scenery and dialect are more closely related to Zeeland than to Holland. On the island they speak a form of Zeelandic, namely Goereês in the west and Flakkees in the east.
