Islington is a suburb of the city of Newcastle in the Hunter Region of New South Wales, Australia. Located only 3.4 kilometres (2.1 mi) from the Newcastle CBD on one of Newcastle's major arterial roads, it was initially developed as a residential suburb. Today it includes a small industrial area and is adjacent to the Newcastle campus of the Hunter Institute of Technology. Its southeastern border is occupied entirely by the Hunter and Newcastle and Central Coast railway lines. The suburb has one railway station, which is shared with, and named after, adjacent Hamilton.
