Terms for Syriac Christians are endonymic (native) and exonymic (foreign) terms, that are used as designations for Syriac Christians, as adherents of Syriac Christianity. In its widest scope, Syriac Christianity encompass all Christian denominations that follow East Syriac Rite or West Syriac Rite, and thus use Classical Syriac as their main liturgical language. Traditional divisions among Syriac Christians along denominational lines are reflected in the use of various theological and ecclesiological designations, both historical and modern. Specific terms such as: Jacobites, Saint Thomas Syrian Christians, Maronites, Melkites, Nasranis, and Nestorians have been used in reference to distinctive groups and branches of Eastern Christianity, including those of Syriac liturgical and linguistic traditions. Some of those terms are polysemic, and their uses have been a subject of terminological disputes between different communities, and also among scholars.

The East Syriac Rite, or East Syrian Rite, is an Eastern Christian liturgical rite that employs the Divine Liturgy of Saints Addai and Mari and utilizes the East Syriac dialect as its liturgical language. It is one of the two main liturgical rites of Syriac Christianity, along with the West Syriac Rite.
