North 1 West is a rugby union league at the sixth level within the English league system. The league is made up of teams from north west England and the Isle of Man; principally consisting of the English counties of Cheshire, Cumbria, Greater Manchester, Lancashire and Merseyside. The league was known as North Division 2 when it was first created back in 1987 and was a single division. It has since split into two regional leagues, with North West 1 and its compatriot North 1 East being the longest running versions of the division.
