The National League System comprises the six levels of the English football league system immediately below the level of the English Football League. It comes under the jurisdiction of the Football Association. The National League System has a hierarchical format with promotion and relegation between leagues at different levels.

The system underwent a rearrangement from 2004 to 2008 and was rearranged again in 2018. Phase one went into operation in 2004–05. At the start of the 2006–07 season, phase two was introduced, and a further phase three started from 2007–08 with the starting of a second Step 4 league in the north of England. Phase four took effect in 2018–19. Ahead of the 2020-21 season, Step 7 was abolished, being replaced by feeder leagues overseen by local county FAs.
