1962 Hessian state election

The 1962 Hessian state election was held on 11 November 1962 to elect the 5th Landtag of Hesse. The outgoing government was a coalition of the Social Democratic Party (SPD) and All-German Party (GDP) led by Minister-President Georg-August Zinn.

The result was a landslide for the SPD, which won an absolute majority of both votes and seats for the first time. The opposition Christian Democratic Union (CDU) slid to 29%, while the Free Democratic Party (FDP) recorded small gains. The SPD's coalition partner the GDP, formed by a merger of the GB/BHE and DP the previous year, retained six seats but failed to capture as many votes as the two partners had separately in 1958. Despite its majority, the SPD maintained its coalition with the GDP and continued in office.

Electoral system
The Landtag was elected via mixed-member proportional representation. 48 members were elected in single-member constituencies via first-past-the-post voting, and 48 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.

Background
In the previous election held on 23 November 1958, the SPD retained a clear first place with 44% of the vote despite a substantial swing to the CDU resulting from the collapse of the FDP vote, which fell to 10%. The SPD's coalition partner the GB/BHE remained steady on 7% and the government continued in office.
