Catholicos of the East and Malankara Metropolitan are the titles used by the Malankara Orthodox Syrian Church, which is also called the Indian Orthodox Church, for the same bishop holding two offices of Catholicos of the East and Malankara Metropolitan. The term "Catholicos" is derived from the Greek word Katholikos (Καθολικός), meaning "Universal Bishop". His Holiness Baselius Marthoma Mathews III is the present Catholicos of the East and Malankara Metropolitan.

Geevarghese Mar Dionysius of Vattasseril popularly known as Vattasseril Thirumeni was a bishop of the Malankara Church and 15th Malankara Metropolitan. In 2003, the Church declared Mar Dionysius as a saint.
