The Diocese of Brooklyn is a diocese of the 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.
The Bishop of the Diocese of Brooklyn and Queens, Bishop Anthony DiMarzio, 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 and Queens on February 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.
The opening of the Brooklyn Navy Yard in 1801 drew a number of immigrants, largely Catholics from Northern Ireland, especially from Derry and Donegal. They would cross the East River to attend services at St. Peter's Church on Barclay Street. Periodically, Rev. John Power or others would come to celebrate Mass at the home of William Purcell or at Dempsey's Blooming Grove Garden on Fulton St. The Church of St. James was erected in 1822. In July, 1841, Father Johann Stephen Raffeiner, from the Tyrol, began the German parish of the Most Holy Trinity on a part of the farm of the old Dutch Meserole family in the Bushwick section. Holy Cross Cemetery was opened in 1849. In 1853, Archbishop John Hughes appointed his vicar-general, Irish-born John Loughlin, former pastor of St. Patrick's on Mulberry St. as bishop of the new diocese. Loughlin chose St. James as his cathedral.
During his episcopate, Loughlin founded 120 parishes. Plans to build the larger Cathedral of the Immaculate Conception were deferred in favor of orphanages, schools, and hospitals. He was succeeded in 1892, by Bishop Charles Edward McDonnell, former chancellor of the Archdiocese of New York. The Diocese of Brooklyn served at that time 250,000 Catholics. With the increase in the number of immigrants of various nationalities, McDonnell founded a number of national churches which ministered to parishioners in their own language. To this end, he invited several religious institutes into the diocese, including the Redemptorists, Benedictines, Franciscans (including the Minor Conventuals and Capuchins), Jesuits, Sisters of the Holy Family of Nazareth, Missionary Sisters of the Sacred Heart, Daughters of Wisdom, and Sisters of the Holy Infant Jesus. He also built three hospitals. Camp Wycoff and Camp Black, set up during the Spanish–American War were attended by local clergy.
Thomas Edmund Molloy was named the third Bishop of Brooklyn on November 21, 1921. In 1930 Bishop Molloy established the Seminary of the Immaculate Conception. The Diocese of Rockville Centre was split off from Brooklyn April 6, 1957. Ten days later, Bryan Joseph McEntegart became the next Bishop of Brooklyn. He built six high schools, Cathedral Preparatory Seminary, and a hospital. He improve outreach to the growing Hispanic population, he sent priests and religious to study Spanish language and culture. Bishop Francis Mugavero experience as former head Brooklyn's Catholic Charities was reflected in his episcopate. In 1971, Mugavero established the Catholic Migration Office to serve the needs of immigrants and refugees living in Brooklyn and Queens. The Nehemiah project produced affordable housing in Brownsville.
In September 2018, the Diocese of Brooklyn and Queens agreed to a record $27.5 million settlement for sex abuse allegations. On February 15, 2019, the Diocese of Brooklyn and Queens made public a list of 108 clergy who were "credibly accused" of committing  some of whom have also been convicted for there crimes. Along with the list, Bishop Nicholas DiMarzio also issued a letter of apology, asking for forgiveness.
