The Northern League is a men's football league in north east England. Having been founded in 1889, it is the second-oldest football league in the world still in existence after the English Football League.

It contains two divisions; Division One and Division Two. Division One sits on the ninth tier of the English football league system, five divisions below the Football League. These leagues cover the historic counties of Durham, Northumberland, Cumberland and Yorkshire's North Riding. The champion club of Division One is promoted to the lower division of the Northern Premier League.
