The OCA has its origins in a mission established by eight Russian Orthodox monks in Alaska, then part of Russian America, in 1794. This grew into a full diocese of the Russian Orthodox Church after the United States purchased Alaska from Russia in 1867. By the late 19th century, the Russian Orthodox Church had grown in other areas of the United States due to the arrival of immigrants from areas of Eastern and Central Europe, many of them formerly of the Eastern Catholic Churches ("Greek Catholics"), and from the Middle East. These immigrants, regardless of nationality or ethnic background, were united under a single North American diocese of the Russian Orthodox Church.

During the [[World War II|Second World War]], the Patriarchate of Moscow unsuccessfully attempted to regain control of the groups which were located abroad. After it resumed its communication with Moscow in the early 1960s, and after it was granted [[autocephaly]] in 1970, the Metropolia became known as the [[Orthodox Church in America]].<ref>{{Cite web|url=https://www.oca.org/history-archives/oca-history-intro|title=A History and Introduction of the Orthodox Church in America|website=www.oca.org|accessdate=25 December 2022}}</ref> But its autocephalous status is not universally recognized. The [[Ecumenical Patriarch of Constantinople|Ecumenical Patriarch]] (who has jurisdiction over the [[Greek Orthodox Archdiocese of America]]) and some other jurisdictions have not officially accepted it. The Ecumenical Patriarch and the other jurisdictions remain in [[Communion (Christian)|communion]] with the OCA. The Patriarchate of Moscow thereby renounced its former canonical claims in the United States and Canada; it also acknowledged the establishment of an autonomous church in Japan in 1970.
