The Pan-Orthodox Council, officially referred to as the Holy and Great Council of the Orthodox Church, was a synod of set representative bishops of the universally recognised autocephalous local churches of the Eastern Orthodox Church held in Kolymvari, Crete. The Council sat from 19 to 26 June 2016.

A synod is a council of a Christian denomination, usually convened to decide an issue of doctrine, administration or application. The word synod comes from the Ancient Greek σύνοδος 'assembly, meeting'; the term is analogous with the Latin word concilium 'council'. Originally, synods were meetings of bishops, and the word is still used in that sense in Catholicism, Oriental Orthodoxy and Eastern Orthodoxy. In modern usage, the word often refers to the governing body of a particular church, whether its members are meeting or not. It is also sometimes used to refer to a church that is governed by a synod.
