Erected in 1966 by Pope Paul VI, the diocese was split off from the Archdiocese of Paris and the Diocese of Versailles. Its territory comprises the department of Seine-Saint-Denis. The diocese is a suffragan of the Archdiocese of Paris.

As of 2020, the Archdiocese was preparing to twin with the Archdiocese of Owando in the Republic of Congo. This came after a visit from Mgr Pascal Delannoy to the Archdiocese of Owando in July 2020.
