The term Synaxis ("gathering together" in Greek; Slavonic, Sobor) may refer to any of the following:
- In general, any gathering of the faithful or clergy of the Orthodox Church for liturgical or administrative purposes, e.g., a synod or one of the divine services.
- More specifically, a gathering to celebrate the Divine Liturgy on the day following a major feast in honor of the saints involved in the primary celebration (e.g., on December 26, the day following the Nativity of Christ is the Synaxis of the Theotokos).
- Also in Slavonic, Cathedrals are also known as Sobors.
