The Northumberland Coalfield is a coalfield in north-east England. It is continuous with the Durham Coalfield to its south. It extends from Shilbottle in the north to the boundary with County Durham along the River Tyne in the south, beyond which is the Durham Coalfield.
The two contiguous coalfield areas were often referred to as the Durham and Northumberland Coalfield(s) or as the Great Northern Coalfield.
