The Northern Premier League, known in recent years as the UniBond League under a title sponsorship contract, is one of the regional English football leagues which sits directly below the regional conference. Due to restructuring, from 2005 onwards its champions have been promoted to the Conference North division rather than the Conference National.

The Northern Premier League was founded in 1968, decades after the other two leagues at what is now the seventh tier of the English football league system - the Southern League and Ryman Isthmian League. At that time it was considered to share the fifth tier with these leagues as well as the established Northern League.

Over the next two decades, the NPL successfully displaced its older rival to become the preeminent regional competition in northern England, with the Northern League eventually forced to accept status as feeder league to the NPL. The creation of what is now the Conference in 1979 and the Conference's addition of regional divisions in 2004 have effectively "demoted" the NPL by two tiers.
