 The name may derive from its bubbling springs resulting in the Middle Ages place name “Hwerwyl” noted in AD 955, possibly meaning “kettle springs” or “cauldron springs.” Pronunciation of the name has ranged from “Hurrell” to “Wer-rel” to present-day “Wher-well.”

Before the Dissolution, the parish of Wherwell was in the hands of an important abbey of Benedictine nuns, whose abbess was Lady of the Manor of an area much larger than the existing parish.The town is associated with the Cockatrice.The story is that the cockatrice terrorised the village until it was imprisoned in the dungeons below Wherwell Priory.
