London 3 Eastern Counties is an English rugby union league that is at the eighth level of the English rugby union system and is available to club sides based in Cambridgeshire, Norfolk and Suffolk (Eastern Counties). Promoted teams move up to London 2 North East with league champions going up automatically and the runners up playing a playoff against the runners up from London 3 Essex, while demoted teams usually drop down to Eastern Counties 1, with new teams also coming up from this league, although only 1st XV sides are allowed in London 3 Eastern Counties. Each year all clubs in the division also take part in the RFU Senior Vase - a level 8 national competition.
