The 2009 European Parliament election in Sweden was held on 7 June 2009 and determined the makeup of the Swedish delegation to the European Parliament. The election was held using a modified form of the Sainte-Laguë method of party-list proportional representation using the entire country as a single electoral constituency. There is a threshold limit of 4 percent for Swedish elections to the European Parliament, so that any party not receiving at least four percent of the votes will not be allocated any seats.

The 2004 European Parliament election in Sweden was the election of MEP representing Sweden constituency for the 2004-2009 term of the European Parliament. It was part of the wider 2004 European election. The vote took place on 13 June. The ruling Social Democrats polled poorly, but virtually all the established parties lost ground to the eurosceptic June List.
