The East Syriac Rite, also known as the Chaldean or Assyrian Rite, is a liturgical tradition of the Eastern Christian churches primarily associated with the Assyrian Church of the East, the Chaldean Catholic Church, and the Syro-Malabar Catholic Church. This rite is characterized by its use of the Syriac language and its distinct liturgical practices, which trace back to early Christian communities in Mesopotamia and Persia.
