The 1984–85 season was the 70th season of the Isthmian League, which is an English football competition featuring semi-professional and amateur clubs from London, East and South East England.
The league consisted of three divisions. After 19 clubs, mainly from the Athenian League joined the league, Division Two was divided into two sections.
Also, it was the first Isthmian League season as an Alliance Premier League feeder league. Sutton United were champions, winning their second Isthmian League title. Wycombe Wanderers were promoted to the APL, as Sutton United and Worthing were ineligible for promotion. Epping Town resigned from the league before their last game of the season and folded; their record was expunged.
