The Northern Ireland Executive is the devolved government of Northern Ireland, an administrative branch of the legislature – the Northern Ireland Assembly. It is answerable to the assembly and was initially established according to the terms of the Northern Ireland Act 1998, which followed the Good Friday Agreement. The executive is referred to in the legislation as the Executive Committee of the assembly and is an example of consociationalist ("power-sharing") government.

The Northern Ireland Assembly, often referred to by the metonym Stormont, is the devolved legislature of Northern Ireland. It has power to legislate in a wide range of areas that are not explicitly reserved to the Parliament of the United Kingdom, and to appoint the Northern Ireland Executive. It sits at Parliament Buildings at Stormont in Belfast.
