Flash is a village within the Staffordshire Moorlands, England, and the Peak District National Park. It is currently the highest recognised village in the United Kingdom. Population details taken at the 2011 census can be found under Quarnford. It was an early centre for Wesleyanism.

Flash is the main village in Quarnford Parish. It lies just off the A53 main road about 4 miles southwest of Buxton. It is on the southern slope of the highest ground on Axe Edge Moor, which rises to a peak of 551m. The parish forms the Staffordshire corner of Three Shire Head, a tripoint marked by a packhorse bridge on a tributary of the River Dane, where Staffordshire, Derbyshire and Cheshire meet.

At 463 metres (1,519 ft) above sea level, Flash claims to be the highest village in Great Britain. In 2007 the claim was upheld by the BBC, which settled a dispute with its rival claimant, Wanlockhead in Dumfries and Galloway. The Ordnance Survey measured the highest house in each village and Flash was higher, although the results were disputed by residents of the Scottish village.
