The 1920 County Championship was the 27th officially organised running of the County Championship. Middlesex County Cricket Club won their second championship title.

The method used in the table reverted to that of 1914 except that in drawn matches, two points were awarded for the first innings winners and no points to the first innings losers. The match between Derbyshire and Nottinghamshire was abandoned without a ball being bowled and is included in the NR column.

Table Five points were awarded for a win. Two points were awarded for "winning" the first innings of a drawn match. Final placings were decided by calculating the percentage of possible points. + County Championship tableTeamPldWLDWFDLFNRPts%PCMiddlesex 20 15 2 1 2 0 77 77.00Lancashire 28 19 5 1 1 2 97 74.61Surrey 24 15 6 2 0 1 79 68.69Yorkshire 28 15 6 3 0 4 81 67.50Kent 26 16 6 1 2 1 82 65.50Sussex 30 18 8 0 2 2 90 64.28Nottinghamshire 20 10 6 2 0 2 54 60.00Gloucestershire 20 8 9 0 0 3 40 47.05Essex 24 9 9 0 4 2 45 40.90Somerset 20 7 10 2 1 0 39 39.00Hampshire 26 7 14 3 1 1 41 32.80Warwickshire 26 7 13 2 2 2 39 32.50Leicestershire 24 7 14 0 1 2 35 31.81Northamptonshire 20 3 16 0 1 0 15 15.00Worcestershire 18 1 16 0 0 1 5 5.88Derbyshire 18 0 17 0 0 1 0 0.00
