The Umbrian regional election of 1975 took place on 15 June 1975.
The Italian Communist Party was by far the largest party, gaining almost twice the votes of Christian Democracy. After the election, Pietro Conti, the incumbent Communist President, continued to govern the Region at the head of a left-wing coalition with the Italian Socialist Party (Popular Democratic Front). In 1976 Conti was replaced by Germano Marri, a Communist too.
