The Conference of Regions and Autonomous Provinces, originally named "Conference of Presidents of Regions and Autonomous Provinces", is a political body of coordination between the regions of Italy and, chiefly, their presidents. Established in Pomezia, Lazio on 15–16 January 1981, the Conference is composed of 21 members, including the representatives of the autonomous provinces of Trentino and South Tyrol, forming the Region of Trentino-Alto Adige/Südtirol, and has since been the official seat of interregional institutional dialogue.
