List of members of the United Nations Security Council

Current membership

;Permanent members

;Non-permanent members

Regional Groups

]]

The ten non-permanent seats have the following distribution:

• African Group: 3 members
• Asia-Pacific Group: 2 members
• Eastern European Group: 1 member
• Latin American and Caribbean Group (GRULAC): 2 members
• 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.

;Electoral timetable

• The representative of Arab nations alternates between these two spaces.

The odd/even distribution was effectively decided by the January 1946 and 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 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).

Membership by year

Permanent

Non-permanent (1946–1965)

Non-permanent (1966–present)

The African Union uses an internal rotation system to distribute seats based on its subregions:

• 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 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. The Arab nation seat is starred below.

The Western European and Others Group in part contains three caucusing subgroups (Benelux, the Nordic countries, and CANZ), whose candidates informally coordinate with each other. 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.

List by number of years as Security Council member ==

This list contains the 139 United Nations member states so far elected to the United Nations Security Council, including the five permanent members, all listed by number of years each country has so far spent on the UNSC. Of all the members, 6 have so far ceased to exist, leaving the list with 133 modern nations. These, combined with the 60 modern nations that have never been elected to the UNSC to date (see Non-members, below), make up the 193 current members of the UN.
