The 1970 Piedmontese regional election took place on 7–8 June 1970.
Christian Democracy was by far the largest party in the Regional Council of Piedmont. After the election, it formed an organic centre-left government with the Italian Socialist Party, the Unitary Socialist Party, and the Italian Republican Party. The regional government was led by Edoardo Calleri di Sala until 1973, and then by Gianni Oberto Tarena, both members of Christian Democracy.
