Eastern Counties 4 was an English level 12 Rugby Union league that was divided into two regional divisions - north and south - with teams from Cambridgeshire, Norfolk, Suffolk and Essex taking part. Promoted teams used to move up to the relevant division in Eastern Counties 3 and relegation was to Eastern Counties 5 until that division was cancelled at the end of the 1996–97 season. The league was originally abolished in 1999–00 due to East Counties restructuring and teams moved up to higher divisions, only to be reinstated in 2014-15 due to further league restructuring that allowed more 2nd and 3rd teams to take part. It was abolished again at the end of the 2016–17 season.
