The Roman Catholic Archdiocese of Lille (Latin: Diocesis Insulensis) is an archdiocese of the Latin Rite of the Roman Catholic church in France. Erected in 1913 as the Diocese of Lille, the archdiocese encompasses the arrondissements of Dunkerque and Lille, within the department of Nord in the Region of Nord-Pas-de-Calais. The current Archbishop of Lille is Laurent Bernard Marie Ulrich, appointed in February 2008; he is one of the two vice presidents of the Conference of Bishops of France.
Originally the diocese was a suffragan to the Archdiocese of Cambrai, but the diocese was elevated to a metropolitan archdiocese by Pope Benedict XVI on March 29, 2008, with the suffragan sees of the Archdiocese of Cambrai and the Diocese of Arras.[1]
