The subdivisions of Belfast are a series of divisions of Belfast, Northern Ireland that are used for a variety of cultural, electoral, planning and residential purposes. The city is traditionally divided into four main areas based on the cardinal points of a compass, each of which form the basis of constituencies for general elections: North Belfast, East Belfast, South Belfast, and West Belfast. These four areas meet at Belfast City Centre. The second traditional divide is that formed by the River Lagan, with the northern bank of the River being part of County Antrim, while the southern bank is part of County Down.
