Counties 1 Yorkshire is an English rugby union division, the seventh tier of the domestic competition, and the top level for local rugby union in parts of Yorkshire. The champions are automatically promoted to Regional 2 North East (formerly North 1 East), a division with a wider geographical area that also encompasses northeast England. The runners-up participate in a playoff against the 2nd place team from the equivalent regional league, Counties 1 Durham & Northumberland, for promotion to Regional 2 North East. The bottom two clubs are relegated to Counties 2 Yorkshire.
Each season a team from Counties 1 Yorkshire is picked to take part in the RFU Intermediate Cup - a national competition for clubs at level 7.
