Syro-Malabar Catholic Eparchy of Hosur

The Syro-Malabar Catholic Eparchy of Hosur-Mylapore is an Eastern Syriac Catholic eparchy headquartered in Tamil Nadu, India, under the Syro-Malabar Catholic Church. It was established by Pope Francis on 10 October 2017, and Mar Sebastian Pozholiparampil was appointed its first bishop. The cathedral is St. Antony's Syro-Malabar Catholic Cathedral Church at Noothenchery and the bishop's chancellory is at St. Thomas Pastoral Centre Ayanavaram.

The Syro Malabar Church is not a language-based community. It is an Oriental (East Syriac Rite) Catholic church, in full communion with the Church of Rome.

Before the creation of this Eparchy, the Chennai Mission was founded in 1981 to serve the Syro-Malabar community in Chennai (Madras). Priests from the Eparchy of Irinjalakkuda volunteered their time to travel to Chennai to provide members who were present in the cities for work and studies.

The Diocese of Hosur was blessed with a new priest, Fr. Shebin Chazhoor. He is from Perambur, St.Joseph Parish. He has completed his minor seminary at Irinjalakuda St.Paul's Minor Seminary. Later, he completed bph from Mary Matha Major Seminary, Thrissur. He took his BTh from Papal Seminary, Pune.
