The European Parliament election of 2009 in Germany was the German part of the European Parliament election, 2009. The voting was held on Sunday, 7 June. A total of 26 parties competed for the 99 seats reserved for Germany in the European Parliament. In the previous election of 2004, the six parties which were represented in the German national parliament (Bundestag) from 2005 to 2013, had entered the European Parliament by overcoming the 5% election threshold. The same parties entered the European Parliament this time. None of the other parties managed to gain more than 1.7%, but together the small parties exceeded 10% for the first time. At 43.3%, the voter turnout was just over the all-time low in the previous European election in Germany (43.0%).
Of particular interest in the European elections was the performance of the conservative CSU. The party only stands for election in the state of Bavaria, instead of its nationwide "sister party", CDU, where it has traditionally been the dominating party, winning absolute majorities for decades. As the CSU's share of votes has to be above 5% on the national level in order to gain seats in the European Parliament, it must gain at least 35% of the Bavarian electorate to pass this threshold. While the CSU had still won 58% in the 2003 Bavaria state election, in the state elections in 2008, its share plummeted to only 43.4%, which was only about 6% on the national level. Despite these fears, in this European election, the CSU gained 7.2% on the national level.
