The 2004 United Nations Security Council election was held on 15 October 2004 at United Nations Headquarters in New York City during the 59th session of the United Nations General Assembly. The General Assembly elected five non-permanent members of the UN Security Council for two-year terms commencing on 1 January 2005.
The five candidate nations elected were Argentina, Denmark, Greece, Japan, and Tanzania.
In accordance with the General Assembly's rules for the geographic distribution of the non-permanent members of the Security Council, and established practice, the members were to be elected as follows: one from Africa, one from Asia, one from Latin American and the Caribbean, and two from Western Europe and Other States.
Before voting, the representative from Eritrea took the floor to formally withdraw his country's candidacy. The country has never been elected to the UN Security Council. Consequently, to Eritrea's withdrawal, all the available seats would be elected without any serious contest. The five declared candidates therefore easily obtained the required 2/3 majority in the General Assembly.
Voting proceeded by secret ballot. For each geographic group, each member state could vote for as many candidates as were to be elected. There were 189 ballots in each of the three elections.
