List of official County Championship winners

Surrey County Cricket Club are the current champions, claiming the title in the 2024 season.

[1] The sport soon became popular through the rest of the country, and by the end of the 18th century, the game was being played nationwide.

[6] Qualification rules were introduced in 1873, and for a long time this was considered the start of the County Championship, but the "Champion County" continued to be inconsistently awarded as late as 1886, when Cricket Magazine named Surrey champions, while most other publications agreed upon Nottinghamshire.

[7] After a meeting of the principal clubs' secretaries in 1889, a method of ranking the teams was agreed upon, and the 1890 season is considered the first official competing of the County Championship.

Long periods of dominance continued after World War II: Surrey were champions seven years running during the 1950s, and Yorkshire then won seven of the following ten championships.
