Jamaica coalition (German: Jamaika-Koalition; also known as the Jamaica alliance, Jamaica traffic light, black traffic light or Schwampel) is a term in German politics describing a coalition among the parties of the Christian Democratic Union/Christian Social Union (CDU/CSU), Free Democratic Party (FDP), and the Green Party.
The term refers to the coincidence that the symbolic colors of the parties in such a coalition—black for the conservative CDU/CSU, yellow for the liberal FDP, and green for the Green Party—are also the colors of the flag of Jamaica. It also alludes to the perception (from a German point of view) of such an alliance as an "exotic" constellation.
After the German federal election in 2005, a Jamaica coalition became mathematically possible and was initially discussed, but the Free Democrats decided they would rather remain in opposition than form a coalition with the SPD or the Greens.
At the state level, the Greens announced in October 2009 that they would support a CDU/FDP coalition in Saarland, forming Germany's first Jamaica coalition in state government. This move was partly prompted by desire to prevent an SPD minority government in Saarland dependent upon support from Die Linke. The Saarland coalition collapsed in January 2012.
A Jamaica coalition is currently in power in the state of Schleswig-Holstein. After the Schleswig-Holstein state election, 2017, CDU leader Daniel Günther became Minister President by forming a coalition with the Free Democrats led by Wolfgang Kubicki and the Greens led by Monika Heinold.
