The Diocese of Brooklyn is a diocese of the Roman Catholic Church in the U.S. state of New York. It is headquartered in Brooklyn and its territory encompasses the New York City boroughs of Brooklyn and Queens. It is a suffragan diocese of the Archdiocese of New York. The diocesan cathedral is the Cathedral Basilica of St. James in Downtown Brooklyn and its co-cathedral is the Co-Cathedral of St. Joseph in Prospect Heights. The current diocesan bishop is Nicholas Anthony DiMarzio.


Brooklyn is one of the few dioceses in the United States that is made up of 100% urban territory.

The Bishop of Brooklyn presides from both the Cathedral Basilica of St. James and the Co-Cathedral of St. Joseph.

This atypical arrangement was required due to the small size of the Cathedral Basilica of St. James. St. Joseph's church was designated as a Co-Cathedral for the Diocese of Brooklyn on Feb. 14, 2013 by Pope Benedict XVI after Bishop Nicholas DiMarzio petitioned the Vatican.


The diocese was established in 1853 out of the territory of the Archdiocese of New York, at a time when Brooklyn was still a separate city from New York City. It originally included all of Long Island, but its present-day territory was established in 1957 when Nassau and Suffolk Counties were split to form the Diocese of Rockville Centre.

On Wednesday, May 2, 2012, Pope Benedict XVI named two priests as Auxiliary Bishops of Brooklyn.
