The Isthmian League is a regional football league covering London and South East England. It is more commonly known by the name of its official title sponsor as the Ryman League, and has in previous years been variously known (in chronological order) as the Rothmans Isthmian League, Berger Isthmian League, Servowarm Isthmian League, Vauxhall-Opel League, Vauxhall League, Diadora League and ICIS League.

The league was founded in 1905, and was strongly dedicated to amateurism. The champions did not even receive a trophy, league policy being that the honour sufficed. Teams less able to compete financially thus gravitated to it rather than the Southern League, while those with ambition and money would move in the opposite direction.

Although the league established itself as one of the strongest leagues in the country, routinely providing the winners of the FA Amateur Cup, it was still seen as being at a lower level than the Southern League and Northern Premier League which were the top regional semi-professional leagues.
