The Malankara Rite is the form of the West Syriac liturgical rite practiced by several churches of the Saint Thomas Christian community in Kerala, India. West Syriac liturgy was brought to India by the Syriac Orthodox Bishop of Jerusalem, Gregorios Abdal Jaleel, in 1665; in the following decades the Malankara Rite emerged as the liturgy of the Malankara Church, one of the two churches that evolved from the split in the Saint Thomas Christian community in the 17th century. Today it is practiced by the various churches that descend from the Malankara Church, namely the Malankara Mar Thoma Syrian Church, Malankara Orthodox Syrian Church, the Jacobite Syrian Christian Church, the Syro-Malankara Catholic Church and the Malabar Independent Syrian Church.

The Malankara Orthodox Syrian Church (MOSC) also known as the Indian Orthodox Church (IOC) or simply as the Malankara Church, is an autocephalous Oriental Orthodox church headquartered in Devalokam, near Kottayam, India. It serves India's Saint Thomas Christian population. According to tradition, these communities originated in the missions of Thomas the Apostle in the 1st century. It employs the Malankara Rite, an Indian form of the West Syriac liturgical rite.
