Belas Knap is a neolithic chambered long barrow, situated on Cleeve Hill, near Cheltenham and Winchcombe, in Gloucestershire, England. It is a scheduled ancient monument in the care of English Heritage but managed by Gloucestershire County Council. "Belas" is possibly derived from the Latin word bellus, 'beautiful', which could describe the hill or its view. "Knap" is derived from the Old English for the top, crest, or summit of a hill.
It is a type of monument known as the Cotswold Severn Cairn, all of which have a similar trapezoid shape, and are found scattered along the River Severn. Belas Knap is described in the English Heritage designation listing statement as an "outstanding example representing a group of long barrows
commonly referred to as the Cotswold-Severn group".
