The 2017 Lower Saxony state election was held on 15 October 2017 to elect the 18th Landtag of Lower Saxony. The incumbent coalition government of the Social Democratic Party (SPD) and The Greens led by Minister-President Stephan Weil was defeated. Though the SPD became the largest party in the Landtag largely fueled by the personal popularity of Weil, their gains were offset by losses for the Greens, depriving the government of its majority. The SPD subsequently formed a grand coalition with the Christian Democratic Union (CDU), and Weil continued as Minister-President.
This was the last election, state or federal, in which the SPD gained seats or increased their share of the popular vote until the 2021 German federal election and 2021 Mecklenburg-Vorpommern state election which both took place on the same day in September 2021.
