The 1966 Hessian state election was held on 6 November 1966 to elect the 6th Landtag of Hesse. The outgoing government was a majority of the Social Democratic Party (SPD) and All-German Party (GDP) led by Minister-President Georg-August Zinn.

The SPD retained its majority and remained stable on 51%. The opposition Christian Democratic Union (CDU) slipped to 26%, and the Free Democratic Party (FDP) 10%. The GDP, which had been in government with the SPD since 1955, fell to 4% and lost its representation in the Landtag. In its place the new radical right-wing National Democratic Party (NPD), led by former FDP politician Heinrich Fassbender, won 8% and 8 seats. This marked the party's first entry into a state parliament and attracted great attention and concern both domestically and internationally. After the election, the SPD chose to govern alone and Minister-President Zinn continued in office.
