The 1970 Hessian state election was held on 8 November 1970 to elect the 7th Landtag of Hesse. The outgoing government was a majority of the Social Democratic Party (SPD) led by Minister-President Albert Osswald.

The opposition Christian Democratic Union (CDU), which had taken a hard line against the SPD under new leader Alfred Dregger, recorded a major swing of 13 percentage points in its favour, to the detriment of the SPD and National Democratic Party, the latter losing all its seats after a single term in the Landtag. The SPD remained the largest party with 46%, and subsequently formed a coalition with the Free Democratic Party, following in the footsteps of the federal government formed the previous year.

The Landtag was elected via mixed-member proportional representation. The size of the Landtag was increased in this election from 96 to 110 members. 55 members were elected in single-member constituencies via first-past-the-post voting, and 55 then allocated using compensatory proportional representation. A single ballot was used for both. An electoral threshold of 5% of valid votes is applied to the Landtag; parties that fall below this threshold are ineligible to receive seats.

In the previous election held on 6 November 1966, the SPD retained its majority with 51% of the vote. The CDU and FDP both stagnated on 26% and 10% respectively, while the new right-wing NPD capitalised on discontent over the economy and the major parties and entered the Landtag with 8%. This marked the party's first success in an election and was followed by a string of similar showings in other states over the following two years. In October 1969, long-serving Minister-President Georg-August Zinn resigned after 19 years in office after suffering a severe stroke. He was succeeded by finance minister Albert Osswald.
