Counties 4 Berks/Bucks & Oxon (formerly Berks, Bucks and Oxon Division 2) 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, becoming the third division of the league structure with promoted teams going into Berks/Bucks & Oxon 1 and there being no relegation.

Further league restructuring in 2011 saw Berks/Bucks & Oxon 2 become one league instead of two regional divisions and newly created divisions below it meant that relegation was introduced. Changes above the division meant that 1st teams were split from 2nd, 3rd and 4th teams and Berks/Bucks & Oxon 1 was the furthest teams in Berks/Bucks & Oxon 2 and below could go in the system.

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. A Central division was added ahead of season 2024-25. Promotion is to Counties 3 Berks/Bucks & Oxon (North) or Counties 3 Berks/Bucks & Oxon (South) depending on location. Relegation is to the merit leagues.

For the new season the league was further sub-divided into three five club competitions with the addition of a Central division.

Departing were Harwell and Bicester II, promoted to Counties 3 Berks/Bucks & Oxon (North). Grove II (3rd) did not return for the new campaign. Chinnor IV (4th) and Littlemore (6th) were level transferred to the new Central division.
