Burnfoot River Shingle and Wydon Nabb is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, North East England.

Wydon Nabb is an escarpment displaying the Haltwhistle Dyke, a magmatic intrusion of igneous dolerite set amidst sedimentary sandstone and shale.

Amongst these are found a number of species associated with limestone including kidney vetch (Anthyllis vulneraria), purging flax (Linum catharticum) and small scabious (Scabiosa columbaria).

Ash (Fraxinus excelsior), hazel (Corylus avellana) and sessile oak (Quercus petraea) form woodlands at the outer margins of the site.

Invasive species are encroaching on the site in part because of lower levels of heavy metals in the contemporary river, (most mining having ceased in the watershed) and due to insufficient intervention.
