The Archdiocese of Auch-Condom-Lectoure-Lombez, more commonly known as the Archdiocese of Auch, is a Latin Church ecclesiastical territory or archdiocese of the Catholic Church in France. The archdiocese now comprises the department of Gers in south-west France. The archdiocese is a suffragan of the Archdiocese of Toulouse, and the current bishop, who therefore does not wear the pallium, is Maurice Marcel Gardès, appointed in 2004.
