The Council of Chalcedon (Concilium Chalcedonense;, Synodos tēs Chalkēdonos) was the fourth ecumenical council of the Christian Church.

Whilst this judgment marked a significant turning point in the Christological debates, it also generated heated disagreements between the Council and the Oriental Orthodox Church, who did not agree with such conduct or proceedings.

The Church of the East split after the Council of Ephesus (431) and Oriental Orthodoxy split after the Council of Chalcedon (451) over differences in Christology, while the Eastern Orthodox Church and the Catholic Church separated in the East–West Schism (1054), especially over the authority of the bishop of Rome.

These variations are a reflection of the range of traditions, and of the councils that have convened on the subject.

Its main accomplishments were settlement of the Christological issue of the divine nature of God the Son and his relationship to God the Father, the construction of the first part of the Nicene Creed, mandating uniform observance of the date of Easter, and promulgation of early canon law.
