The 1989 Britannic Assurance County Championship was the 90th officially organised running of the County Championship. Worcestershire won their second successive Championship title. A sub-standard pitch at Southchurch Park, for which Essex were docked the 25 points, cost them the Championship.
The Championship was sponsored by Britannic Assurance for the sixth time.
