The West Syriac Rite, also called the Syro-Antiochian Rite and the West Syrian Rite, is an Eastern Christian liturgical rite that employs the Divine Liturgy of Saint James in the West Syriac dialect. It is practised in the Maronite Church, the Syriac Orthodox Church, the Syriac Catholic Church and various Malankara Churches of India. It is one of two main liturgical rites of Syriac Christianity, the other being the East Syriac Rite. It originated in the ancient Patriarchate of Antioch. It has more anaphoras than any other rite.

Eastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in the Eastern Mediterranean region or locations further east, south or north. The term does not describe a single communion or religious denomination. Eastern Christianity is a category distinguished from Western Christianity, which is composed of those Christian traditions and churches that originally developed further west.
