Counties 3 Berks/Bucks & Oxon (formerly Berks, Bucks and Oxon Division 1) is an English rugby union league featuring teams from Berkshire, Buckinghamshire and Oxfordshire.
The division was created in 2004–05 as part of a complete overhaul of the Berks/Bucks & Oxon league, with a large number of 2nd, 3rd and 4th teams entering at various levels, and was divided into north and south regions, with the original Berks/Bucks & Oxon 1 division becoming the Berks/Bucks & Oxon Premier and Berks/Bucks & Oxon 1 becoming, in effect, division 2 of the system. Rather confusingly promoted 1st teams would go up into the Berks/Bucks & Oxon Premier while 2nd, 3rd and 4th teams would move into Berks/Bucks & Oxon Premier A.
The league would be restructured further in 2011–12 with the re-introduction of a new tier 2 competition - the Berks/Bucks & Oxon Championship and the cancellation of Berks/Bucks & Oxon Premier A. This meant that Berks/Bucks & Oxon 1 (now merged into one league instead of two regional ones) would be for lower teams and below only with no chance of promotion to a higher league (although relegation was still possible).
Following the RFU Adult Competition Review the structure changed once more with reserve teams and first teams competing in the same leagues, the competition administered centrally rather than by county constituent bodies and a North / South divisional split. Promotion is to Counties 2 Berks/Bucks & Oxon (North) or Counties 2 Berks/Bucks & Oxon (South) depending on location. Relegation is to Counties 4 Berks/Bucks & Oxon (North) or Counties 4 Berks/Bucks & Oxon (South) again depending on location.
