Kariattil Mar Ouseph (5 May 1742 – 10 September 1786) was the first native Indian to be appointed as Archbishop of the Syrian Catholics in the territory now comprising Kerala, India.

Kariattil was born at Alengad, near Aluva in present-day central Kerala. He had his initial religious education at the Seminary at Alengad. Later he was sent to the Propaganda College of Pontifical Urban University, Rome, in 1755 when he was barely 13 years old. There he was ordained as a priest, and he took Doctorate in Philosophy and Theology from there. He returned to India in 1766. He was then appointed as a Malpan at Alangad Seminary.

Kariattil Malpan took great efforts for the reunion of the Saint Thomas Christians (also known as Syrian Christians or Nasrani) who had split following the Coonen Cross Oath. He made the historic journey to Rome in 1778 together with Paremmakkal Thoma Kathanar to represent the matter with the church authorities there. Kariattil Malpan was consecrated at Lisbon in 1783 and was appointed as Archbishop of Cranganore (Kodungalloor). However, on his way back to India, he died at Goa on 10 September 1786. He was initially buried there and later his mortal remains were transferred to Alengad and were re-interred at St. Mary's Syro-Malabar Catholic Church, Alangad in 1961.

He is the author of two books, viz. Vedatharkkam (Dialectics on Theology) (1768) and Noticias do Reino do Malabar (1780).
