Elections for local government were held in Northern Ireland in May 1977.
The elections saw good performances by the four largest parties: the Ulster Unionist Party (UUP), Social Democratic and Labour Party (SDLP), Alliance Party of Northern Ireland and Democratic Unionist Party (DUP), while smaller parties failed to make a breakthrough.  The DUP took control of their first council, Ballymena, while the UUP retained control of Banbridge.  The SDLP lost control of Magherafelt, their only council.
