Discover the Archdiocese of Wilmington

The Roman Catholic Diocese of Wilmington (LatinDioecesis Wilmingtoniensis) is an ecclesiastical territory or diocese of the Roman Catholic Church in the eastern United Statesand comprises the entire state of Delaware and the Eastern Shore of Maryland (i.e. the parts of the Delmarva Peninsula not in Virginia). It is led by Bishop William Francis Malooly, whose seat is the Cathedral of Saint Peter in the City of Wilmington.

The Diocese publishes a newspaper, The Dialog, which underwent a circulation and format transformation in 2011 as a result of financial pressures.


The first Roman Catholic mission in Delaware was established in 1804 by Rev. Patrick Kenney on the site of the Coffee Run Cemetery in Mill Creek, Delaware. The Coffee Run Mission Site was listed on the National Register of Historic Places in 1973. The diocese was canonically erected on March 3, 1868 by Pope Pius IX. It took its territories from theArchdiocese of Baltimore and the then Diocese of Philadelphia, and also received the 2 eastern-shore counties of Virginia, thus extending all the way down the Delmarva Peninsula. The Virginia part was returned to the Diocese of Richmond in 1974, leaving the Diocese of Wilmington with all of Delaware and the 9 eastern-shore counties of Maryland. In 2009, the diocese filed for Chapter 11 bankruptcy in the face of financial liabilities from lawsuits alleging sexual abuse by priests. A settlement was reached in February 2011, implementation of which had not yet occurred by May 2011.
