Threlkeld is a village and civil parish in the north of the Lake District in Cumbria, England, to the east of Keswick. It lies at the southern foot of Blencathra, one of the more prominent fells in the northern Lake District, and to the north of the River Glenderamackin.
Historically a part of Cumberland, Threlkeld formerly had its own railway station on the Cockermouth, Keswick and Penrith Railway, on the opposite side of the valley, next to the (closed) Threlkeld Quarry, at the foot of Clough Head. Today the railway line is a footpath and cycle track. Three rows of terraced houses, which used to accommodate the quarry workers, stand near the station. The Threlkeld Quarry and Mining Museum is open nearby and operates the narrow gauge Threlkeld Quarry Railway for tourists to enjoy.
Two pubs are located opposite each other in the village: The Salutation and the Horse and Farrier. There is also a Coffee Shop, a vibrant Village Hall, and a small church, St Mary's, in the village.
