Long Newnton is a small village and civil parish in Gloucestershire, England, situated on the main road (B4014) between Malmesbury (2 km NW) and Tetbury (5 km S). It is near the SW end of the Cotswolds. In 2010 its population was estimated to be 199, increasing to 211 at the 2011 census, 109 males and 102 females.
Historically the village was also known as "Long Newton".
The Fosse Way forms part of the parish boundary and also the county boundary with Wiltshire. Long Newnton was one of several parishes which were transferred from Wiltshire to Gloucestershire in 1930.
The village has no shops: just a church (Holy Trinity Church) and between 30 and 60 houses. The nearest large towns are Cheltenham and Swindon. Long Newnton is about an hour from Bristol, Bath, Gloucester and Oxford. Close to Long Newnton is the Estcourt estate which is now owned by an Arabian horse owner. However Estcourt House and other features named for the Estcourt family are actually in the neighbouring parishes of Shipton Moyne and Tetbury Upton. The village was associated for hundreds of years with the Estcourt family, and the church living was in the gift of the family. The Estcourt fund finances extra-curricular activities for young people aged 13 and over living in Long Newnton.
