The 2013 Bill Beaumont Cup, also known as Bill Beaumont Cup Division One, was the 113th version of the annual, English rugby union, County Championship organized by the RFU for the top tier English counties. Each county drew its players from rugby union clubs from the third tier and below of the English rugby union league system (typically National League 1, National League 2 South or National League 2 North). The counties were divided into two regional pools with the winners of each pool meeting in the final held at Twickenham Stadium. New counties to the competition included Durham County (north) and Kent (south) who won their respective groups in the 2012 County Championship Plate. Hertfordshire were the defending champions.
