The Abruzzo regional election of 1970 took place on 7–8 June 1970.
Christian Democracy was by far the largest party, gaining more than twice the share of vote of the Italian Communist Party, which came distantly second. The position of President of Abruzzo was held by Ugo Crescenzi (1970–1972), Giustino De Cecco (1972–1973), Ugo Crescenzi (1973–1974) and again Ugo Crescenzi (1974–1975), all Christian Democrats.
