The 1920 County Championship was the 27th officially organised running of the County Championship. Middlesex County Cricket Club won their second championship title.[1]
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.
