The Chamber of Regions is one of the two Chambers of the Congress of Local and Regional Authorities of the Council of Europe, the other being the Chamber of Local Authorities.
The Chamber is the voice of regional authorities in the Council of Europe. It consists of 306 representatives and substitutes from the Council's 46 member states, who either hold regional mandate from elections or are answerable to a directly elected assembly.
The Congress of Local and Regional Authorities is the pan-European political assembly representing local and regional authorities from the forty-six member states of the Council of Europe. Known from 1957 to 1983 as the Conference of Local Authorities of Europe and from 1983 to 1994 as the Standing Conference of Local and Regional Authorities of Europe, its role is to promote local and regional democracy, improve local and regional governance, and strengthen authorities' self-government according to the principles laid down in the European Charter of Local Self-Government.
The Congress is made up of two chambers, the Chamber of Local Authorities and the Chamber of Regions, and holds its plenary sessions twice a year at the Palace of Europe in Strasbourg, where its permanent Secretariat is based.
