"Mer Hayrenik" (Armenian: Մեր Հայրենիք, "Our Fatherland") is the national anthem of the Republic of Armenia. Adopted on 1 July 1991, it was also the national anthem of the First Republic of Armenia (1918–1920), the first modern Armenian state.

The lyrics of the anthem are adapted from a version of Song of an Italian girl (Armenian: Իտալացի աղջկա երգը Italats’i aghjka yergy, written in 1859) by Mikael Nalbandian (1829–1866). Later set to music by composer Barsegh Kanachyan (1885–1967).
