What is the English football league system?
The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with five teams from Wales, one from Guernsey, one from Jersey and one from the Isle of Man also competing. The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system, the Premier League. Below that are levels 2–4 organised by the English Football League, then the National League System from levels 5–10 administered by the FA, and thereafter feeder leagues run by relevant county FAs on an ad hoc basis.

The exact number of clubs varies from year to year as clubs join and leave leagues, merge, or fold altogether, but an estimated average of 15 clubs per division implies that more than 7,000 teams of nearly 5,300 clubs are members of a league in the English men's football league system.

As there are no official definitions of any level below 11, any references to the structure at level 12 and below should not be regarded as definitive.

The pyramid for women's football in England runs separately into ten tiers, and some England-based men's clubs play outside the English football league system.
