Berks, Bucks and Oxon Championship was a division at level 9 of the English rugby union system featuring teams from Berkshire, Buckinghamshire and Oxfordshire. Promoted teams moved up to the Berks/Bucks & Oxon Premier and there was no relegation. Each year three teams (one each from the Berkshire, Buckinghamshire and Oxfordshire unions) were picked to take part in the RFU Junior Vase (a national cup competition for clubs at levels 9-12).
