The Battle of the Beanfield took place over several hours on 1 June 1985, when Wiltshire Police prevented a convoy of several hundred New Age travellers from setting up the 1985 Stonehenge Free Festival in Wiltshire, England. The police were enforcing a High Court injunction obtained by the authorities prohibiting the 1985 festival from taking place. Around 1300 police officers took part in the operation against approximately 600 travellers.

On the day the convoy of travellers encountered resistance at a police road block seven miles from Stonehenge. Police then smashed the windows of traveller vehicles and some travellers were arrested whilst the rest broke into an adjacent field. A stand-off consequently developed that persisted for several hours. At least one police officer has claimed that travellers hurled missiles including petrol bombs at the police during this period.
