The 1988 Britannic Assurance County Championship was the 89th officially organised running of the County Championship. Worcestershire won the Championship title.[1] [2] Matches played over four days were introduced to the competition this season. Each county was scheduled to play sixteen three-day matches, one against each other county, and six four-day matches. The four-day matches were played at the start and end of the season. This resulted in a total of twenty-two games for each county, a decrease of two from the number played in 1987.[3]
