Hayk Nahapet (Armenian: Հայկ; also known as Haig; transliterated as Haik) is the legendary patriarch and founder of the Armenian nation. His story is told in the History of Armenia attributed to the Armenian historian Movses Khorenatsi (410 to 490 AD).

The name of the patriarch, Հայկ Hayk is not exactly homophonous with the name for "Armenia", Հայք Hayk’. Հայք Hayk’ is the nominative plural in Classical Armenian of հայ (hay), the Armenian term for "Armenian." Some claim that the etymology of Hayq' (Հայք) from Hayk (Հայկ) is impossible and that origin of the term Hay ("Armenian") is verifiable. Nevertheless, Hayk and Hayq are usually^[who?] connected to hay (հայ) and hayer (հայեր, the nominative plural in Modern Armenian), the self-designation of the Armenians.

Hayk would then be an aitiological founding figure, like e.g. Asshur for the Assyrians, Indra for the Indians, etc. One of Hayk's most famous scions, Aram, settled in Eastern Armenia from the Mitanni kingdom (Western Armenia), when Sargon II mentions a king of part of Armenia who bore the (Armenian-Indo-Iranian) name Bagatadi ("Theodore").
