Khoren I Paroyian (Armenian: Խորեն Ա. Բարոյան ) (24 November 1914 in Nicosia – 9 February 1983 in Antelias) was the Catholicos of the Holy See of Cilicia, from 1963 to 1983. He was born in Nicosia, Cyprus with the birth name of Mesrob. He had four brothers and a sister. His parents were originally from Kharpert. He was elected as Catholicos on 12 May 1963 after the death of Zareh I.
In 1977, because of his poor health, Catholicos Khoren I decided to have a Coadjutor to ensure that after his death there would be no disruption in the management of the church. Karekin Sarkisian, the archbishop and Pontifical Legate of the Eastern Prelacy of the United States was elected as Catholicos Coadjutor (in Armenian աթոռակից կաթողիկոս), a post the latter served assisting Catholicos Khoren I in his duties.
Upon the death of Khoren I, Karekin was installed as Catholicos Karekin II of Cilicia.
