Swiss federal election, 2007
Elections to the Swiss Federal Assembly, the federal parliament of Switzerland, were held on Sunday, 21 October 2007. In a few cantons, a second round of the elections to the Council of States was held on 11 November, 18 November, and 25 November 2007. For the 48th legislative term of the federal parliament (2007–2011), voters in 26 cantons elected all 200 members of the National Council as well as 43 out of 46 members of the Council of States. The other three members of the Council of States for that term of service were elected at an earlier date.
The results reflected yet another rise in support for the strongest party, the right-wing populist Swiss People's Party, at 29% of the popular vote, and the growth of the Green and Green Liberal parties at the expense of the Social Democrats.
National Council 
The Swiss People's Party successfully came out of the election as the strongest party, rising another 2.3% to 29.0% of the popular vote. Among the left-wing parties, support of the Social Democrats eroded to the benefit of the Green and Green Liberal parties.
The right-wing parties won 64 seats made up of the SVP with 62 seats and a single seat of the Christian right Federal Democratic Union and the regional Ticino League respectively. The left-wing parties won 65 seats, with 43 of the Social Democrats, 20 of the Green party, and the Christian-left Christian Social Party and the far-left Labour Party with a single seat each. The centrist parties won 71 seats, with the CVP and the centre-right FDP each having won 31 seats, and the remaining 9 seats won by minor parties: Liberals, 4 seats; Green Liberals, 3 seats; Evangelical People's Party, 2 seats.
59 of 200 seats (29.5%) were won by women, as compared to 50 in 2003. Ricardo Lumengo (Social Democrats, born in Angola) is notable as the first black Swiss national councillor. 23 incumbents did not get re-elected and lost their mandate, among them Zürich right wing politician Ulrich Schlüer (SVP).The turnout of the election was 48,9% a rise of 3,7% from the previous elections in 2003.

- The date of the election of the members of the Council of States is a matter of cantonal law. 24 cantons have chosen to let the elections coincide with the federally regulated National Council elections. Two cantons are electing their members of the Council of States at an earlier date: Zug reelected its incumbents Peter Bieri and Rolf Schweiger on 29 October 2006, while Appenzell Innerrhoden elected Ivo Bischofsberger as its one representative in that Council on 29 April 2007.
