Lancs/Cheshire Division 1 (usually referred to as Lancs/Cheshire 1) was a regional English Rugby Union league for teams from Cheshire, Merseyside, Lancashire and Greater Manchester, ranked at tier 8 of the English league system. The top two clubs are promoted to North 2 West and the bottom two clubs are relegated to Lancs/Cheshire 2. Each season two teams from Lancs/Cheshire 1 are picked to take part in the RFU Senior Vase (a national competition for clubs at level 8) - one affiliated with the Cheshire RFU, the other with the Lancashire RFU.
