Vahan Mamikonian (Armenian: Վահան Մամիկոնյան) (440/445 – 503/510) was an Armenian nobleman from the Mamikonian family. In 481 he rebelled against the Sasanian Empire that controlled the eastern part of Armenia known as Persian Armenia. He was appointed as marzban (governor) of Persian Armenia in 485 and remained in that post until his death around 503-510.

Since 387, the kingdom of Armenia was divided into two zones of influence, Byzantine Armenia and Persian Armenia. In addition, in 428, the last Arsacid monarch, Artaxias IV, was deposed by his overlord Bahram V at the request of the Armenian nakharars, thus starting the Marzpanate period in Persian Armenia. Very quickly, the Armenians were disillusioned: in 449, Yazdegerd II ordered the nobility to convert to Zoroastrianism. The Armenians revolted under the leadership of Vardan Mamikonian, but were defeated on 2 June 451 (or May 26) at the battle of Avarayr; most nakharars who participated in the revolt were deported to Ctesiphon.

Vahan was born around 440 - 445. He was the eldest son of Hmayeak Mamikonian and Dzoyk, he had 3 younger siblings named Vard, Vasak, and Artaxias. His father was killed by guerrillas at Tayk in the aftermath of the battle of Avarayr. Vahan, along with Vasak and Artaxias, was captured by the marzban of Armenia and was deported to Ctesiphon; sentenced to apostasy, and was "weakened in their faith," according to his childhood friend and contemporary historian Ghazar Parpetsi.
