Khoren I Mesrop Paroyan (Armenian: Խորեն Ա. Բարոյան ) (24 November 1914, Nicosia - 9 February 1983, Antelias) was the Catholicos of the Holy See of Cilicia, from 1963 to 1983. He was preceded by Zareh I. Because of poor health Karekin II (Cilicia) was elected as Catholicos Coadjutor in 1977, a post he served assisting Catholicos Khoren I until the latter's death, when Karekin succeeded him as Karekin II of Cilicia.
