Norton, also known as Norton-on-Tees, is a market town in the Borough of Stockton-on-Tees, in County Durham, England. The suburbs of Roseworth and Ragworth are notable areas of the town. Billingham Beck is to the east of the town, the beck flows to the south-east. The town also contains the areas of Wolviston and Wynyard which are to the north of the town and are wards of the town. The town had a population of 20,829 in the 2011 Census.

The area's centre dates back to at least the Anglo-Saxon period. It was the centre of an ancient parish that once included the chapelry of Stockton, which became a separate parish in 1713.

In 1982, the chance discovery of human bones by school children playing on a rope swing near the Mill Lane area of the town, led to the unearthing of an Anglo-Saxon pagan cemetery. Excavations in 1984 revealed 120 burials (117 inhumations and 3 cremations) in graves that contained assorted personal items such as spears, belt buckles and brooches. The remains and objects collected suggest the site was dated to around AD 540–610.

To the south end of High Street, the Victoria Jubilee Memorial Cross stands where the market place was once situated. The red sandstone Anglian style cross commemorates Queen Victoria's Diamond Jubilee in 1897. Further along, and on the opposite side of the High Street are the Fox almshouses, also founded in 1897 at the bequest of local brewer John Henry Fox.

Norton was an ancient parish, which also included the chapelry of Stockton, which became a separate parish in 1713. Most of the parish of Norton, including the main built-up area, was absorbed into the municipal borough and parish of Stockton in 1913. A residual civil parish of Norton, covering just the more rural western part of the old parish, continued to exist until 1 April 1968 when it was abolished and absorbed into the County Borough of Teesside along with Stockton and other areas. In 1961 the parish had a population of 416. It is now in the unparished area of Stockton-on-Tees.

At the north end of Norton centre there is a large village green with a duckpond, surrounded by mostly Georgian houses and cottages. The ancient parish church of St. Mary the Virgin stands on the west side of the village Green.

Norton's wide and tree-lined High Street has a number of shops, hairdressers, boutiques, cafés, a library, photographic studio and a traditional fish & chips shop, as well as a mixture of 18th century and 19th century townhouses, cottages and modern apartments. Away from the village lie the housing estates of Albany, Glebe, Crooksbarn and Norton Grange (originally Blue Hall).

St Mary the Virgin, the ancient parish church that stands on the village green, is the only cruciform Anglo-Saxon church in northern England. Its crossing tower with eight triangular head windows has a battlemented top of later date, and there is a 14th-century effigy of a knight in chainmail. Residing under the church floor there is claimed to be an escape tunnel used by the Saxons and priests when in danger, though it is more probably a drainage culvert. The tunnel leads under the church floor and Norton Green, eventually surfacing in the Albany housing estate. The church floor was recently renovated and Saxon remains and artefacts were discovered in the tunnel entrance. St Mary's was until the Reformation a Catholic church – which is true of all English churches pre-dating the Reformation.
