Immigration of Maronite Christianity from Greater Syria to the United States began during the latter part of the nineteenth century. When they were able to obtain a priest, communities were established under the jurisdiction of the local Latin Bishops.

Pope Paul VI, with the Apostolic Constitution Cum supremi of January 10, 1966, established the Maronite Apostolic Exarchate for the Maronite faithful of the United States. Francis Mansour Zayek was appointed the first bishop in a decree of the Sacred Congregation for the Eastern Churches dated January 27, 1966. The See city was Detroit, Michigan, with a Cathedral under the patronage of St Maron. At that time, the Exarchate was a suffragan of the Archdiocese of Detroit.

On November 29, 1971, Pope Paul VI, with the Apostolic Constitution Quae spes, the Exarchate was elevated to the status of an Eparchy, with the name of Eparchy of St. Maron of Detroit. With a decree from the Sacred Congregation of the Eastern Churches dated June 27, 1977, the see of the Eparchy of St. Maron was transferred to Brooklyn, New York, with the cathedral under the patronage of Our Lady of Lebanon. The name of the Eparchy was modified to Eparchy of St. Maron of Brooklyn. On December 10, 1982, Pope John Paul II accorded the title of "Archbishop ad personam" to Bishop Zayek as recognition of his personal contributions to the Catholic Church.

Lebanon. by Archbishop Francis Mansour Zayek, representing the Maronite Patriarch Nasrallah Boutros Sfeir, enthroned Bishop Chedid on the 24th of June of that year.

On December 5, 2000, the Pope accepted the resignation of Bishop John Chedid due to canonical age, and appointed Chorbishop Robert Joseph Shaheen to the see. Bishop Shaheen was ordained and installed Eparch on February 15, 2001, by Patriarch Nasrallah Peter Sfeir in the Cathedral Basilica of the Archdiocese of Saint Louis, Missouri. Soon after, the Congregation for the Oriental Churches approved the relocation of the eparchy's offices to St. Louis and the elevation of the Church of St. Raphael to the co-cathedral of the eparchy.
