Tidworth is a garrison town and civil parish in south-east Wiltshire, England, on the eastern edge of Salisbury Plain.

Evidence of prehistoric activity in the area is in the form of several sites with bowl barrows, including a group of seven;[3] and an Iron Age hillfort at Sidbury Hill in the north of the parish.

[8] In 1897 the War Office bought the house and grounds, together with land to the north which gave access to Salisbury Plain for Army training.

[9] Extensive barracks were built in the early 20th century, largely in South Tidworth but spreading across the boundary to the north.

An Ordnance Survey map of 1958 labels the parishes as North Tidworth and South Tedworth.

[citation needed] In the 21st century the population of the town increased as the barracks now known as Tidworth Camp expanded, in particular following the return of units from Germany in 2019 and 2020 under the Army Basing Plan.

There was a church dedicated to St Mary at South Tidworth from the 13th or 14th centuries, but by 1784 it was in poor condition and Thomas Assheton Smith the elder, owner of Tedworth House, was given permission to demolish it.

[31] For Westminster elections, the parish falls in the East Wiltshire constituency, which has been represented since 2024 by Danny Kruger for the Conservatives.

[32] Tidworth has a small commercial area containing two supermarkets (a Lidl and a large Tesco), two veterinary surgeries, a pharmacy, and other shops and services.

In 2003 a new medical centre was completed, the cost being split between the Ministry of Defence and the NHS, as it serves the armed forces and their dependants within the surrounding area.

Castledown FM, a community radio station, broadcasts to Tidworth and Ludgershall from studios in the grounds of Wellington Academy.

The academy has a sixth form college, an all-weather sports pitch, and dedicated Combined Cadet Force facilities.
