Counties 1 Durham & Northumberland

Counties 1 Durham & Northumberland, formerly known as Durham/Northumberland 1 is an English amateur rugby union competition. The league consists of twelve clubs, and is the seventh tier of the English rugby union system, as one of the 16 regional leagues, though is the highest level of local rugby in the North East of England. The champions are automatically promoted to North 1 East, a division with a wider geographical area that also encompasses the Yorkshire region. The runners-up participate in a play-off against the runners-up from the equivalent regional league, Counties 1 Yorkshire, for promotion. The bottom two are relegated to Counties 2 Durham & Northumberland.

Each season, two teams from the league are selected to take part in the RFU Intermediate Cup, a national competition for clubs in the seventh tier: one is affiliated with the Durham County RFU, the other is affiliated with the Northumberland RFU.

Durham/Northumberland 1 (1993–2000)
The creation of National 5 North for the 1993–94 season meant that Durham/Northumberland 1 dropped to being a tier 10 league. A further restructure at the end of the 1995–96 season, which included the cancellation of National 5 North and the addition of North East 3 at tier 9, saw Durham/Northumberland 1 remain at tier 10 with promotion to the new North 3 East league.

Durham/Northumberland 1 (2000–2022)
Northern league restructuring by the RFU at the end of the 1999–2000 season saw the cancellation of North East 1, North East 2 and North East 3 (tiers 7–9). This meant that Durham/Northumberland 1 became a tier 7 league, with promotion to North 2 East (currently North 1 East).
