Longbridge Deverill is a village and civil parish about 2.5 miles (4.0 km) south of Warminster in Wiltshire, England.

[4] Iron Age settlements include a site on high ground at Cow Down in the east of the parish, where there are foundations of a large enclosure.

A short length of north–south road, probably a section of the route from Bath to Poole, survives on Brimsdown Hill and became part of the boundary with Maiden Bradley parish.

[11] In 1655, Sir James Thynne provided a terrace of three two-storey almshouses southeast of Longbridge Deverill church, built in rubble stone with slate roofs.

[12] In the 19th century a shortage of employment led to emigration to America, Canada or Australia; 181 people left from Longbridge.

[16] Today the church is a Grade II* listed building[14] and forms part of the Cley Hill benefice.

[17] Holy Trinity Church at Crockerton was built in 1843 as a chapel of ease at the expense of the Dowager Marchioness of Bath, to designs of Wyatt and Brandon.

It falls within the area of the Wiltshire Council unitary authority, which is responsible for all significant local government functions.

This ward starts in the north at Upton Scudamore, avoids Warminster, then stretches south through Longbridge Deverell to end at Kingston Deverill.
