2024 Brandenburg state election

The election to the state parliament Landtag of Brandenburg of 22 September 2024 was the third state election within Germany in the month of September 2024, three weeks after the state elections in Thuringia and in Saxony, all part of former East Germany. The outgoing government was a black-red-green "flag of Kenya" coalition consisting of the Social Democratic Party (SPD), the Christian Democratic Union (CDU) and The Greens, led by Minister-President Dietmar Woidke of the SPD.

Despite contrary polling showing them consistently trailing in second place, the SPD, which has governed Brandenburg since its 1990 re-establishment, remained the largest party with a five percentage point swing in its favour. The Alternative for Germany received a swing of six points and won just over 29% of the vote. The Sahra Wagenknecht Alliance (BSW) debuted at 13.5%, followed by the CDU which declined to 12%. The outgoing government narrowly lost its majority as the Greens collapsed and fell short of the 5% electoral threshold, losing all their seats. The Left also suffered major losses and fell out of the Landtag, as did the Free Voters. The FDP, which had won 9.3% of the vote in the 2021 German federal election in Brandenburg, fell to 0.8% of the vote, their worst result in any state election ever, eclipsing the 0.9% of the vote in Saxony two weeks prior.
