Zalmoxis also known as Salmoxis (Σάλμοξις), Zalmoxes (Ζάλμοξες), Zamolxis (Ζάμολξις), Samolxis (Σάμολξις), Zamolxes (Ζάμολξες), or Zamolxe (Ζάμολξε) is a divinity of the Getae and Dacians, mentioned by Herodotus in his Histories Book IV, 93–96, written before 425 BC.

The Getae or Gets were a Thracian-related tribe that once inhabited the regions to either side of the Lower Danube, in what is today northern Bulgaria and southern Romania. Although it is believed that the Getae were related to their westward neighbours, the Dacians, several scholars, especially in the Romanian historiography, posit that the Getae and the Dacians were the same people.
