Kent 4 was an EnglishRugby Union league that was the fourth tier for clubs in south-east London and Kent. Promoted teams went up to Kent 3 and there was no relegation.

Kent 4 was brought back in 2000 but after just one season, the six team division folded for the second time and all teams were automatically promoted to Kent 3.
