Mumps Hall was an inn at the confluence of the Poltross Burn and the River Irthing, a site now at the centre of the village of Gilsland in Cumbria.
It appears in Celia Fiennes' account of her journey through northern England in 1689; she called it "a sorry place of entertainment" and it was described, but not named, by Walter Scott in his novel Guy Mannering: “The alehouse, for it was no better, was situated at the bottom of a little dell, through which trilled a small rivulet.
It was shaded by a large ash tree, against which the clay-built shed that served the purpose of a stable was erected, and upon which it seemed partly to recline.
It was a hedge alehouse, where the border farmers of either country often stopped to refresh themselves and their nags, in their way to and from the fairs and trysts in Cumberland, and especially those who came from or went to Scotland, through a barren and lonely district, without either road or pathway, emphatically called the Waste of Bewcastle.
Mumps Hall features in Scott's novel Guy Mannering as the meeting place of Brown and Meg Merrilees, in the company of Dandy Dinmont.
