Duncairn ward is located in north Belfast, stretching inland from the Shore Road along the Antrim Road corridor. The area is primarily residential, containing a mix of housing types from Victorian terraces to more modern apartment developments. It is bounded by significant roads and includes neighbourhoods such as Tigers Bay and the lower stretches of the New Lodge area.
The ward encompasses several key local institutions, including the Mater Infirmorum Hospital. A notable landmark is the Crumlin Road Courthouse, a imposing Victorian-era building that stands as a historic symbol of the city's judicial past. Green space is provided by the Waterworks Park, which features two reservoirs and recreational facilities for the community.
