Roman Catholic Diocese of Rockville Centre, diocese of the Catholic Church in the United States
The Roman Catholic Diocese of Rockville Centre is a church district covering Nassau and Suffolk Counties on Long Island in New York. It includes more than 130 parishes and churches serving around 1.2 million baptized Catholics, along with numerous schools, hospitals, and Catholic Charities programs throughout the region.
The diocese was established in 1957, separating from the Diocese of Brooklyn after decades of growth. This followed the arrival of Irish and other Catholic immigrants in the 1800s, when the first church in the area was built in Westbury in 1840.
The diocese takes its name from Rockville Centre, where the cathedral is located. Churches and community centers throughout the area serve as gathering places where people celebrate their faith, attend mass on weekends, and participate in charity events that strengthen local bonds.
The diocese spans Nassau and Suffolk Counties across Long Island with churches and parishes scattered throughout many towns and communities. The diocesan website provides information about mass times, programs, and upcoming events to help visitors and residents stay informed.
The diocese was established in 1957, making it relatively young compared to many other American dioceses. Despite its recent origins, it quickly became one of the largest and most active dioceses in the region, serving more than a million baptized Catholics today.
