The 2004 European election was the sixth election to the European Parliament and the sixth for Germany. The elections were held on 13 June 2004.
The elections saw a heavy defeat for the ruling Social Democratic Party, which polled its lowest share of the vote since World War II. More than half of this loss, however, went to other parties of the left, particularly the Greens. The votes of the opposition conservative parties, the Christian Democratic Union and the Christian Social Union, also fell, though not as sharply as the SPD's. The liberal Free Democratic Party improved its vote and gained representation.
