North-West North 1 was an EnglishRugby Union league which was at the tenth tier of the domestic competition and was available to teams in Cumbria and the northern part of Lancashire. Promoted teams moved up to North-West East/North 1 while relegated teams dropped to North-West North 2 until it was disbanded at the end of the 1989–90 season.
North-West North 1 ran for five seasons from 1987 to 1992 until it was cancelled by the RFU as part of their north-west league restructuring. All non-promoted sides from North-West North 1 were transferred into the new Cumbria division (also at tier 10) for the start of the 1992–93 campaign.
