The Maeotian Swamp (, e Maiotis límne; ) was a name applied in antiquity variously to the swamps at the mouth of the Tanais River in Scythia (the modern Don in southern Russia) and to the entire Sea of Azov which it forms there. (The sea was also known as the [] and by other names.) The people who lived around the sea were known as the Maeotians, although it remains unclear which was named for which.
