1982 Hessian state election

The Landtag was elected via mixed-member proportional representation. 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 8 October 1978, the incumbent SPD–FDP coalition retained its majority and was renewed for a third term. The CDU remained the largest party, though there was a small swing from them to the SPD. Two small green parties ran for the first time and finished with about 1% each, becoming the largest non-parliamentary parties in the state. They federated into the new national party The Greens in 1980, which ran for the first time in 1982.
