Gedrosia (; ) is the Hellenized name of the part of coastal Baluchistan that roughly corresponds to today's Makran. The area which is named Gedrosia, in books about Alexander the Great and his successors, runs from the Indus River to the southern edge of the Strait of Hormuz. It is directly to the south of the countries of Bactria, Arachosia and Drangiana, to the east of the country of Carmania and due west of the Indus River which formed a natural boundary between it and Western India. The native name of Gedrosia might have been Gwadar as there are two towns by that name and a bay (Gwadar Bay) in central Makran.
