The 1985 Lombard regional election took place on 12 May 1985.
The election was held under proportional representation with provincial constituencies where the largest remainder method with a Droop quota was used.
To ensure more proportionality, the remained votes and seats were transferred at regional level and calculated at large.
After the election Giuseppe Guzzetti was re-elected president for the third time at the head of a center-left coalition comprising also the PSI, the PSDI, the PLI and the PRI.
In 1986 Guzzetti was replaced by Bruno Tabacci, to whom Giuseppe Giovenzana succeeded in 1989.
