The Siunia also known as the Siak or Syunik were a family of ancient Armenian nobles who were the first dynasty to govern as Naxarars in the Syunik Province in Armenia from the 1st century. The Naxarars were descendants of Sisak.
The first known ruler was Valinak Siak (c.330) and his successor was his brother Andok or Andovk (Antiochus, c.340). In 379 Babik (Bagben) the son of Andok, was re-established as a Naxarar by the Mamikonian family. Babik had a sister called Pharantzem who had married the Arsacid Prince Gnel, nephew of the Armenian King Arsaces II (Arshak II) and later married Arsaces II as her second husband. Babik's rule lasted for less than ten years and by about 386 or 387, Dara was deposed by the Sassanid Empire.
Valinak (c.400-409) was followed by Vasak (409-452). Vasak had two sons: Babik (Bagben), Bakur and a daughter who married Vasak’s successor, Varazvahan (452-472). Varazvahan’s son Gelehon ruled from 470-477, who died in 483. Babik (Bagben) who was the brother of Varazvahan became the new Naxarar in 477. Hadz the brother of Gelehon died on September 25 482. The Syunik Province was later governed by Vahan (c.570), Philip (Philipo, c.580), Stephen (Stephanos, c.590-597), Sahak (Issac, c.597) and Grigor (Gregory, until 640).
A cadet branch of the dynasty came to rule the Kingdom of Artsakh as of the 11th century.

Finally, Siunia and Moxoene were ruled by their own, homonymous, dynasties. Of the remaining princes, many were in their day as important, but none perhaps as historically significant, as these; and of these, four dynasties stand out exceeding all the rest in historical importance: the Bagratids, the Mamikonids, the Artsrunis, and the Siunis."
