The Massagetae, or Massageteans (Greek: Μασσαγέται, lat. Massagetai), were an ancient Eastern Iranian nomadic confederation, who inhabited the steppes of Central Asia, north-east of the Caspian Sea (in modern Turkmenistan, western Uzbekistan, and southern Kazakhstan).
The Massagetae are known primarily from the writings of Herodotus who described the Massagetae as living on a sizeable portion of the great plain east of the Caspian Sea. He several times refers to them as living "beyond the River Araxes", which flows through the Caucasus and into the west Caspian. Scholars have offered various explanations for this anomaly. For example, Herodotus may have confused two or more rivers, as he had limited and frequently indirect knowledge of geography.
According to Greek and Roman scholars, the Massagetae were neighboured by the Aspasioi (possibly the Aśvaka) to the north, the Scythians and the Dahae to the west, and the Issedones (possibly the Wusun) to the east. Sogdia (Khorasan) lay to the south.
Many scholars have suggested that the Massagetae were related to the Getae of ancient Eastern Europe and/or the Jats of modern South Asia. A 9th century work by Rabanus MaurusDe Universo states: "The Massagetae are in origin from the tribe of the Scythians, and are called Massagetae, as if heavy, that is, strong Getae." In Central Asian languages such as Middle Persian and Avestan, the prefix massa means "great", "heavy", or "strong".
