The British–Irish Council (BIC) (Irish: Comhairle na Breataine-na hÉireann) is an intergovernmental organisation that aims to improve collaboration between its members in a number of areas including transport, the environment, and energy. Its membership comprises Ireland, the United Kingdom, the devolved governments of Northern Ireland, Scotland and Wales, and the governments of the Crown Dependencies of the UK: Guernsey, Jersey and the Isle of Man. England does not have a devolved administration, and as a result is not individually represented on the council but represented as a member of the UK.

The British and Irish governments, and political parties in Northern Ireland, agreed to form a Council under the British–Irish Agreement, part of the Good Friday Agreement reached in 1998. The council was formally established on 2 December 1999, when the Agreement came into effect. The council's stated aim is to "promote the harmonious and mutually beneficial development of the totality of relationships among the peoples of these islands". The BIC has a standing secretariat, located in Edinburgh, Scotland, and meets in semi-annual summit session and more frequent ministerial meetings.
