The Diocese of Roermond (Latin: Dioecesis Ruremundensis) is a diocese of the Latin Church of the Catholic Church, located in the Netherlands. The diocese is one of the seven suffragan dioceses in the ecclesiastical province of the Metropolitan Archbishop of Utrecht. The territory of the diocese covers the Province of Limburg.
Its cathedral episcopal see is the Cathedral of St. Christopher in Roermond.
Its main pilgrimage sites are Kapel in 't Zand and Valkenburg.
The Dean of Roermond is responsible for the parishes in that city and a few other municipalities in the diocese.

Originally established on 12 May 1559, on territories split off from the Metropolitan Archdiocese of Cologne (Keulen, now in Germany) and Diocese of Liège (Luik, now in Belgium).
During the Napoleonic era, on 15 July 1801 it lost territory to establish the Apostolic Vicariate of Grave–Nijmegen. On 29 November 1801 the diocese was suppressed, its territory being divided between the above vicariate and the establishment of the (German) Diocese of Aachen (Aix-la-Chapelle).
It was re-established in 1840 by the Holy See as (pre-diocesan) Apostolic Vicariate of Limburg. In 1853 it was promoted as Diocese of Roermond and gained territory from the Belgian Diocese of Liège.
During the 1960s, the relatively strong demarcation between the Netherlands' Catholic south and its Calvinist northwest began to diminish. Since the second half of the twentieth century, a rapid secularization and strong loss of religious affiliation have taken place in Limburg.
The diocese has roughly 817,000 registered Catholics (about 72.3% of the population of Limburg). Roughly 3 percent of the population in the Diocese Roermond attends Mass on Sundays[1] (as per official Church (KASKI) data). The Roermond diocese is one of the two in the Netherlands that is in a majority-Catholic region, as per the most recent KASKI data.
