|Full name||Northumberland Rugby Football Union|
The Northumberland Rugby Union is the governing body for rugby union in the historic county of Northumberland, England and one of the constituent bodies of the national Rugby Football Union having been formed in 1880. In addition, the county has won the county championship on two occasions, and finished runners-up on a further five occasions.
The Union was founded in 1880 by six club sides. The six founding members were The Northumberland Football Club (defunct), The (original) Borough of Tynemouth Football Club (defunct), The Northern Football Club, The (original) Gosforth Football Club, The Tynedale Football Club and The Percy Park Football Club.
Northumberland were one of the very few counties to own their own ground. In 1912 they began using the land of the Northumberland County Ground and later built a stadium. Many international fixtures were played there; all County Finals were played at the ground until it was demolished in 1988.
After moving from Scotland where he played for Royal HSFP and Edinburgh, James Robertson then played for Northumberland, a local club - but not the County team. Robertson was the first known black rugby union player.
There are currently 24 clubs  affiliated with the Northumberland RFU, making it one of the smaller unions in England. Most of the clubs in the Northumberland RFU have teams at both senior and junior level and are based either in Northumberland or Tyne and Wear.
The Northumberland RFU currently runs the following competitions for club sides based in Northumberland and Tyne and Wear:
