The 2008 Hessian state election was held on 27 January 2008 to elect the members of the Landtag of Hesse. The incumbent Christian Democratic Union (CDU) government led by Minister-President Roland Koch lost its majority. The result of the election was extremely close but inconclusive, with the CDU winning just 3,500 votes (0.1%) more than the Social Democratic Party (SPD). Due to the entrance of The Left to the Landtag, neither the CDU–FDP or SPD–Green bloc garnered a majority. After a year of failed attempts to form government, a new election was held.

Roland Koch is a German jurist and former conservative politician of the Christian Democratic Union (CDU). He was the 7th Minister President of Hesse from 7 April 1999, immediately becoming the 53rd President of the Bundesrat, completing the term begun by his predecessor as Minister President, Hans Eichel, until his resignation on 31 August 2010. During his time in office, Koch was widely regarded as one of Chancellor Angela Merkel's main rivals within the CDU.
