Mikayel Chamchian (Armenian: Միքայել Չամչյան; 1738–1823) was an Armenian Mekhitarist monk and historian. He is best known for writing a comprehensive and influential history on Armenia in three volumes, which retained its use as a reference work for scholars working in the field of Armenian Studies for over a century.
In 1774 he was appointed instructor of Armenian language in the monastery. In 1779, he wrote Kerakanutiun Haykazian Lezvi (Grammar of the Armenian Language). By 1784, he had finished his Patmutiun Hayots i Skzbane Ashkharhi Minchev tsam diarn (Պատմութիւն Հայոց, Armenian history from the beginning of the world to the year 1784). The work marks the beginning of Romantic Armenian nationalism.
Chamchian provided a chronology for the Armenian patriarchs (as laid down by Movses Khorenatsi in his History of Armenia), dating Haik's battle with Belus, and thus the formation of the Armenian people, to August 11, 2492 BC. He is also the source for the traditionally accepted date for the foundation of official Christiandom in Armenia as AD 301.
In 1795, he was sent back to Constantinople as the resident Mekhitarian representative.
