[[File:UNSC 2024.svg|thumb|Map showing the members of the [[United Nations Security Council]] {{As of|2024|lc=y}}, with [[Permanent members of the United Nations Security Council|permanent members]] ([[China]], [[France]], [[Russia]], the [[United Kingdom]], and the [[United States]]) in blue, and non-permanent members ([[Algeria]], [[Ecuador]], [[Guyana]], [[Japan]], [[Malta]], [[Mozambique]], the [[Republic of Korea]], [[Sierra Leone]], [[Slovenia]], and [[Switzerland]]) in green.]]

Membership of the [[United Nations Security Council]] is held by the five [[Permanent members of the United Nations Security Council|permanent members]] and ten elected, non-permanent members.

Being elected requires a two-thirds majority vote from the [[United Nations General Assembly]]. Elected members hold their place on the council for a two-year term, with five seats contested in even years and five seats contested in odd years. An outgoing member cannot be immediately re-elected.

Elections usually begin in October for a term starting January 1. Because of the two-thirds majority requirement, it is possible for two evenly matched candidates to deadlock with approximately half the vote each, sometimes needing weeks of negotiations to resolve.

Non-permanent seats are distributed geographically, with a certain number of seats allocated to each of the five [[United Nations Regional Groups]].

The ten non-permanent seats have the following distribution:
* [[African Group]]: 3 members
* [[Group of Asia and the Pacific Small Island Developing States|Asia-Pacific Group]]: 2 members
* [[Eastern European Group]]: 1 member
* [[Latin American and Caribbean Group|Latin American and Caribbean Group (GRULAC)]]: 2 members
* [[Western European and Others Group|Western European and Others Group (WEOG)]]: 2 members

In addition, one of the five African/Asian seats is an [[Arab country]], alternating between the two groups. This rule was added in 1967 for it to be applied beginning with 1968.

<nowiki>*</nowiki> The representative of Arab nations alternates between these two spaces.

The odd/even distribution was effectively decided by the [[January 1946 United Nations Security Council election|January 1946]] and [[1965 United Nations Security Council election|1965]] elections (the first ever election, and the first election after the expansion of seats). For each of the six and four members in the newly created seats, the UN General Assembly voted to grant either a 1-year or 2-year term.

== Previous Security Council composition ==
From 1946 to 1965, the Security Council had six non-permanent members. Due to a lack of African and Asian member states, the seats had the following distribution:
* Latin America: 2 members
* [[Commonwealth of Nations]]: 1 member
* Eastern Europe: 1 member
* Middle East: 1 member
* Western Europe: 1 member

As [[decolonization]] increased the number of Asian and African member states without a group, they began to contest other seats: [[Ivory Coast]] substituted a member of the Commonwealth in 1964–1965, the Eastern European seat regularly included Asian countries from 1956, [[Liberia]] took the place of a Western European country in 1961, and [[Mali]] successfully contested the Middle Eastern seat in December 1964 (the Security Council would be expanded before Mali's term began).

An [[Amendments to the United Nations Charter|amendment to the UN Charter]] ratified in 1965 increased the number of non-permanent seats to 10, and the Regional Groups were formalized. The amendment effectively created three African seats and one Asian seat (if treating the Commonwealth seat as a WEOG seat and the Middle Eastern seat as an Asian seat{{efn|In practice, the Commonwealth seat was by then treated as a ''de facto'' African seat.<ref name="thegreenpapers"/>}}).

=== Non-permanent (1966–present) ===
The [[African Group]] uses an internal rotation system to distribute seats based on [[Regions of the African Union|its subregions]]:<ref>{{Cite book|last=Endeley|first=Isaac|date=2009|title=Bloc Politics at the United Nations: The African Group|publisher=University Press of America|isbn=978-0761845584}}</ref><ref>{{Cite thesis|last=Endeley|first=Isaac|date=1998|title=Le Groupe africain à l'ONU dans l'après-guerre froide|url=https://www.collectionscanada.gc.ca/obj/s4/f2/dsk3/ftp05/NQ65306.pdf|degree=PhD|publisher=Université de Montréal|access-date=2024-03-30|language=French}}</ref>
* 1 odd-year seat alternates between Eastern Africa and Southern Africa (only Eastern Africa prior to the creation of the Southern Africa subregion in 1979)
* 1 even-year seat is allocated to Western Africa
* 1 even-year seat alternates between Northern Africa (the [[Arab world|Arab nation]] seat) and Central Africa (with one exception at the beginning in 1966)

Aside from the [[Asia-Pacific Group]] also allocating an Arab nation seat every four years (in even years not divisible by 4), other regional groups do not have their own subregional rotation systems.<ref name="equitable"/><ref name="report2009">{{Cite web|url=https://www.securitycouncilreport.org/research-reports/lookup-c-glkwlemtisg-b-5488243.php|title=Special Research Report No. 1: UN Security Council Elections 2009 : Research Report : Security Council Report}}</ref> The Arab nation seat is starred below.

The Western European and Others Group in part contains three [[caucus]]ing subgroups ([[Benelux]], the [[Nordic countries]], and CANZ{{Efn|Canada, Australia, and New Zealand}}), whose candidates informally coordinate with each other.<ref>{{Cite web|url=https://www.securitycouncilreport.org/research-reports/lookup-c-glKWLeMTIsG-b-2013021.php|title=Special Research Report No. 4: Security Council Elections 2006 : Research Report : Security Council Report}}</ref><ref name="report2009"/> While this has not resulted in a stable rotation system, it effectively guarantees that both seats will never be occupied by a single subgroup at the same time.<ref name="thegreenpapers">[http://www.thegreenpapers.com/ww/UNSecurityCouncil.phtml The United Nations Security Council], The Green Papers Worldwide</ref>

== Non-members ==
The [[United Nations Charter]] requires that elections to the Security Council take into account "the contribution of Members...to the maintenance of international peace and security". As a result, many nations, small or otherwise, have never been on the Security Council. The following list is a summary of all countries, currently 61 modern nations<ref>{{Cite web|title=Countries Never Elected Members|url=https://www.un.org/securitycouncil/content/countries-never-elected-members-security-council|publisher=United Nations|access-date=1 January 2020}}</ref> and three historical ones that have never been a member of the United Nations Security Council. The three [[United Nations member states#Former members|historical UN members]] listed are [[Tanganyika (1961–1964)|Tanganyika]], [[Zanzibar]], and [[Serbia and Montenegro]].
