The Malabar Independent Syrian Church; also known as the Thozhiyur Sabah (Church); is a Christian church centred in Kerala; India. It is one of the churches of the Saint Thomas Christian community; which traces its origins to the evangelical activity of Thomas the Apostle in the 1st century.

Considered part of the Syriac Orthodox Group of churches in India; the church split from the main body of India's Malankara Church in 1771. After a court verdict in 1862; the church was given its current name Malabar Independent Syrian Church.

Today the church remains small; with about 35;000 members; and maintains good relations with the other Malankara churches.
