The 1979–80 Kent Football League season was the fourteenth in the history of the Kent Football League, a football competition featuring teams based in and around the county of Kent in England.
The League structure comprised two divisions: Division One and Division Two with the latter known as the Reserves Section (reserves teams were not permitted in Division One). Additionally there were two league cup competitions: the Challenge Cup for the Division One clubs and another for the teams in Division Two.
Division One
The division featured seventeen clubs which had all competed in the previous season.
After five seasons of being named Medway the club reverted its name to Chatham Town.
The division was won by Chatham Town, (their reserves team were also successful and won the Division Two league and cup double).
At the end of the season both bottom clubs, Ramsgate and Kent Police were re-elected to continue their membership of Division One.
