The village is mentioned in the Domesday Survey when it formed part of the estate of Ralph de Mortimer although evidence of occupation extends back to at least Roman times, as the remains of a temporary marching camp lie near the village.

The name means 'Broom farm/settlement'. '
Bryan' probably refers to one Brian Unspac.

During the First English Civil War, Brampton Bryan Castle was held for Parliament by  Lady Brilliana Harley during the first of two sieges.
The first siege started on 26 July 1643 when Royalists surrounded Brampton Bryan.
Although the village was put to the torch (the church, the parsonage, 40 houses and the castle mills were all burnt down), and the castle left without a roof, the Royalists failed to capture the castle, ending the siege on 9 September.
Lady Brilliana died later that year, probably due to ill health brought on by the siege.
In the spring of 1644, the Royalists began a new siege that lasted for three weeks.
This time the castle defences were so weakened by undermining and battering by artillery, that the Parliamentary governor surrendered the castle.
It was then sacked and burnt, while the garrison was sent to be imprisoned in Royalist-controlled Shrewsbury.

There was also a castle in Pedwardine, south of the main village, that belonged to the Hay family.
