The Orontid dynasty, also known by their native name Eruandid or Yervanduni, was a hereditary Armenian dynasty and the rulers of the successor state to the Iron Age kingdom of Urartu (Ararat). The Orontids established their supremacy over Armenia around the time of the Scythian and Median invasion in the 6th century BC.

The Orontid dynasty (aka Eruandid or Yervanduni) succeeded the Kingdom of Urartu in ancient Armenia and ruled from the 6th to 3rd century BCE. Initially, the Orontids ruled as Persian satraps and the culture, language and political practices of that state were introduced into ancient Armenia.
