Thatcham straddles the River Kennet, the Kennet and Avon Canal and the A4. The parish currently covers the town of Thatcham, with its suburbs of Henwick, Dunston Park and Colthrop, and the village of Crookham including Crookham Common and the eastern ranges of the old RAF Greenham Common airfield. The historic parish once also covered Midgham, Cold Ash, Ashmore Green and Greenham. Thatcham Reed Beds, just to the south of the town, is a site of Special Scientific Interest (SSSI).^[2]

The name may have been derived from that of a Saxon chief called Tace (or perhaps Tac or Tec), who established a village in around 500 AD.^[3] The settlement might have been known as Taceham - ham meaning village in Saxon. However, some of the earliest written references, in c.951 and c.975,^[3][4] records it as Thaecham. The Thaec comes from the Saxon þæc or thaec meaning roof-covering^[5] and the ham has been speculated to be a shortened hamm which would mean a river meadow.^[6]

The area has evidence of occupation dating from prehistoric times^[7] and was listed in the Guinness Book of Records as the strongest claimant to being the oldest continuously inhabited place in Britain. The well-preserved remains of a mesolithic settlement, dating from 8400 to 7700 BCE,^[7] have been found in its vicinity. Evidence also exists of Bronze and Iron Age settlements and of Romano-British activity.

In the Domesday Book of 1086, following the Norman Conquest, the name had altered slightly to Taceham before going through several minor changes until the current form was adopted in the 16th century. The town had a period of great prosperity around 1304,^[8] when the Chapel of St. Thomas the Martyr on the A4, now called the Old Bluecoat School, was granted permission to hold services. At that time the population was larger than that of Newbury.^[3] The chapel is a Grade I listed building.^[9] There is a Norman parish church of St. Mary, which was largely reconstructed in 1857. This is believed to be built on the same site as an earlier Anglo-Saxon church. It was previously known as St. Luke's. The church is a Grade II* listed building.^[10]

In 1121, Henry I founded Reading Abbey and endowed it with many gifts of land, including the Manor of Thatcham. At the same time Thatcham Hundred ceased to exist: the western part was transferred to Faircross Hundred, and the remainder to the Hundred of Reading. In 1141 Thatcham church, previously the property of the Diocese of Salisbury, was granted to Reading Abbey by the Empress Matilda, who at the same time confirmed her father's gift of the manor to the abbey.

During World War II, Thatcham housed one of the biggest Prisoner of War camps in the South, known as camp 1001. Thatcham's population grew rapidly in the second half of the 20th century: from 5,000 in 1951 and 7,500 in 1961 to 22,824 in 2001.^{[citation needed]}

Thatcham railway station is on the Reading to Taunton line, with regular services between Reading and Newbury and between Paddington and Bedwyn, operated by Great Western Railway. The main east–west road through the town is the A4 Bath Road, which runs between London and Bristol. This road has been superseded as a long-distance route by the M4 motorway which runs almost parallel to the A4, about 3 miles (4.8 km) to the north. The closest junction to the town is the Chieveley interchange at Junction 13.

Thatcham is home to non-league football club Thatcham Town, who play their matches at Waterside Park, 300 metres (330 yd) south of the Thatcham railway station. The club reached the final of the FA Vase in the 2017–18 season, becoming the first Berkshire side to reach a national cup final. Thatcham Town Cricket Club is based at a ground on Brownsfield Road, next to the council offices. The Henwick Worthy Sports Ground is the home of the Newbury and Thatcham Hockey Club and the Thatcham Rugby Union Football Club, and plays host to a number of amateur and youth sports.

The town is divided into four wards for West Berkshire Council elections: Thatcham Central, Thatcham North, Thatcham South & Crookham and Thatcham West. Seven councillors represent Thatcham on the West Berkshire Council with the Liberal Democrats having five, and the Conservatives having two.^[14] These wards are used in town council elections, with fourteen Liberal Democrats, three Conservatives, and one Green Party member sitting on the town council.^[15] At national level it is represented, since 2019, by the Conservative MP for Newbury, Laura Farris.^[16]

Local employment is chiefly in light industrial premises, sales and distribution, retail and public sectors.^{[citation needed]}
