Sturminster Newton is a town and civil parish situated on the River Stour in the north of Dorset, England. The town is at the centre of the Blackmore Vale, a large dairy agriculture region around which the town's economy is built, and is known as 'the heart of the Blackmore vale'.

The town has shops, a primary and secondary school – Sturminster Newton High School – and a school and college catering for children with special educational needs. A market is held in the town on Mondays. One of the largest cattle markets in England used to be held here, but it was closed in 1998.

The town is noted for its connections with the authors Thomas Hardy and William Barnes, and as part of the historic West Country Carnival circuit.

Sturminster Newton was recorded in an Anglo-Saxon charter in 968 as Nywetone at Stoure, and in the Domesday Book of 1086 as Newentone. Newton refers to a new farm or estate, and Sturminster to a church (minster) on the Stour. Originally the two parts of the name referred to the settlements on the north and south of the river, but were combined to distinguish the town from Sturminster Marshall and other Newtons. The history of the town and surrounding area has been researched by the Sturminster Newton Heritage Trust, which runs the Sturminster Newton Museum in the Old Market Cross House in the centre of town. The Museum is open to visitors on some days every week.

Hidden on the hill above the bridge over the river are the ruins of Sturminster Newton Castle, a manor house rather than a defensive building. The 14th-century building stands on a crescent shaped mound which could be the site of an Iron Age hillfort. The town and castle were part of Sturminster Newton hundred.

Sturminster Newton is situated at a historic fording point on the River Stour. The ford was replaced in the 16th century with a six-arch stone bridge, and a quarter-kilometre embankment crossing the flood plain. The bridge was widened from 12 to 18 feet (3.7 to 5.5 metres) in 1820. A 19th-century plaque affixed to the bridge states that anyone damaging the bridge would be transported to Australia as a felon.

The Sturminster Newton Heritage Trust runs the Sturminster Newton Mill on the south bank of the river and which has existed since at least 1016. The mill was restored in 1980 and is now a working museum watermill which is open to visitors on some days every week between the end of March and the end of September. The mill resumed commercial production of flour in 2020.

The town centre is built in a mixture of styles, including 17th- and 18th-century thatched cottages, Georgian stone buildings, and 19th-century brick buildings. Set back from the main road is the market square and parish church of St Mary, which was rebuilt in 1486 by the abbots of Glastonbury. The church was heavily modified in the 19th century, but the carved wagon roof remains.

Sturminster Newton railway station was served by the Somerset and Dorset Railway, which ran through the town from 1863 until it was dismantled in 1966 as part of the Beeching Axe. The railway goods yard gave milk trains access to the private sidings of the local creamery. Started in 1913 by local farmers to produce cheddar cheese and pasteurised milk, it was taken over by the Milk Marketing Board in 1937. Milk trains ceased in 1966 on closure of the line, with the creamery remaining in operation until 2000 under successor Dairy Crest. The station and goods yard were demolished in the mid-1970s.

The town is set in the vale on which Thomas Hardy based his fictional Vale of the little dairies (in his novel Tess of the d'Urbervilles) and Sturminster had the largest cattle market in Europe, which stood close to the town centre until it was closed and demolished in 1997.

Sturminster Newton electoral ward elects one member to Dorset Council. The town also has a town council of 11 members.

In the UK parliament, Sturminster is in the North Dorset parliamentary constituency which is currently represented by Simon Hoare of the Conservative party.

Sturminster Newton civil parish covers about 4,550 acres (1,840 hectares) at an elevation of 45 to 119 metres (148 to 390 feet), with the highest ground being in the southeast.

The town is situated on a meander of the River Stour. The larger part of the town (Sturminster) lies on a low limestone ridge to the north side of the river, and includes most shops and services, whilst to the south is the smaller Newton, separated by a wide flood plain.

The geology of the parish comprises Oxford clay in the northwest, Corallian limestone and sands in the northeast, centre and southwest, and Kimmeridge clay in the southeast.

To the southeast of the town are Girdlers Coppice and Piddles Wood, areas of mature woodland that are designated as sites of special scientific interest.
