The Median language was a Western Iranian language, classified as North-Western with Parthian, Baluchi, Kurdish and others.

It was the language of the tribes of the Medes. Although we have no record of the Median language we cannot regard it as differing to any great extent from Old Persian. The Medes and Persians were closely connected, and there is nothing to justify us in looking for the true Median language either in the Old Persian cuneiform writings of the second class or in the Zend Avesta. Median may therefore be considered a dialect of Old Persian.
