Brill is a village and civil parish in Aylesbury Vale district in Buckinghamshire, England, close to the boundary with Oxfordshire. It is about 4 miles (6 km) north-west of Long Crendon and 7 miles (11 km) south-east of Bicester. It has a Royal charter to hold a weekly market, but has not done so for many years.
Brill's name is tautological, being a combination of Brythonic and Anglo Saxon words for 'hill' (Brythonic breg and Anglo Saxon hyll). In the reign of Edward the Confessor it was a town called Bruhella.
