Plakias (Greek: Πλακιάς) is a village on the south coast of the Greek island of Crete, in the Rethymno regional unit, about 30 kilometres south of the city of Rethymno. It is part of the municipal unit Foinikas.

It is surrounded by mountains to the north and the Libyan Sea to the south. The name in Greek means "flat", because the town stands on an alluvial fan of material that has washed down the Kotsifou gorge directly to the north . This material has formed along the sea's edge into a long, fine, gold-hued sand beach, which shelves very gradually out into the bay, making it quite safe for swimming and hence, for family holidays.
