Antiochian Orthodox Christian Archdiocese of North America

The Antiochian Orthodox Christian Archdiocese of North America (AOCANA), often referred to in North America as simply the Antiochian Archdiocese, is the jurisdiction of the Greek Orthodox Church of Antioch in the United States and Canada. Originally under the care of the Russian Orthodox Church, the Syro-Levantine Eastern Orthodox Christian immigrants to the United States and Canada were granted their own jurisdiction under the Church of Antioch in the wake of the Bolshevik Revolution. Internal conflicts divided the Antiochian Orthodox faithful into two parallel archdioceses—those of New York and Toledo—until 1975, when Metropolitan Philip (Saliba) became the sole archbishop of the reunited Antiochian Archdiocese. The Holy Synod of Antioch granted the Archdiocese semi-autonomous status in 2003, and by 2014 it had grown to over 275 parish churches. In 2025, the Archdiocese claimed to have between 84,000 and 380,000 baptized members, "depending on the report and the counting method used." In 2015, the Archdiocese reported having around 100,000 baptized members.

It is one of two Orthodox Christian jurisdictions in North America to currently practice the liturgical Western Rite as well as the Byzantine Rite, along with the Russian Orthodox Church Outside of Russia.
