The 1980 Schweppes County Championship was the 81st officially organised running of the County Championship. Middlesex won the Championship title.[1]
Four matches were abandoned without a ball being bowled and are not included in the table and Leics and Sussex were both awarded 6 points for a drawn match in which the scores were level.[2] The Championship was sponsored by Schweppes for the third time.
