The Tuscan regional election of 1980 took place on 8 June 1980.
Electoral law
Election was held under proportional representation with provincial constituencies where the largest remainder method with a Droop quota was used. To ensure more proportionality, remained votes and seats were transferred at regional level and calculated at-large.
Results
The Italian Communist Party was by far the largest party. After the election Mario Leone (Italian Socialist Party), the incumbent President of the Region, formed a new government with the Italian Communist Party.
In 1983 a government crisis occurred as the relationship between the Communists and the Socialists had become tense at the national level. Communist Gianfranco Bartolini formed a one-party government and then a new coalition government with the Proletarian Unity Party.
