Cotys III (Ancient Greek: Κότυς, Kotys) was a king of the Odrysians in Thrace in the early 3rd-century BC. His one secure attestation is an inscription from Delphi dated to sometime between 276 and 267 BC (usually given as 270/269 BC), in which he is named as the son of Raizdos, his probable predecessor. Scholarship has long associated a coin type struck for a king Cotys on one side and a king Rhescuporis on the other and also a king Cotys, father of a Rhescuporis, named in a decree from Apollonia (Sozopol) with Cotys III. However, these identifications have been doubted, and some scholars have redated both the coin type and the inscription to almost three centuries later. It is therefore uncertain whether Cotys III was succeeded by a son named Rhescuporis.
