Dunston was originally an independent village on the south bank of the River Tyne. It has now been absorbed into the Metropolitan Borough of Gateshead in the English county of Tyne and Wear. Much of Dunston forms part of the inner Gateshead regeneration area.
Dunston is now split into two distinct areas separated by the A1 dual carriageway. Much of the area south of the A1 is known as Dunston Hill.
To the west of Dunston is the site of Dunston Power Station, now demolished. The site is now home to Costco, with the MetroCentre (which is the largest shopping and leisure centre in Britain) occupying the former site of the station's ash ponds. As of 2013, Go North East are constructing a new bus depot to replace their Sunderland Road and Winlaton depots on the eastern part of the power station site. Another Dunston landmark was the Derwent Tower, commonly known as the "Dunston Rocket", a tower block that was once the highest in Gateshead, which was designed by the Owen Luder Partnership and completed in 1973. It was finally demolished in 2012, having always proved unpopular with residents, and fallen into such a poor condition that Gateshead Council decided renovation costs would be prohibitive. Luder also designed the similarly maligned Trinity Centre Multi-Storey Car Park (now also demolished) in Gateshead town centre.
