Office building near UN Headquarters in Turtle Bay from which Nigeria's permanent delegation has operated since UN membership on 7 October 1960. Site of five Security Council non-permanent term workrooms (1966–67, 1978–79, 1994–95, 2010–11, 2014–15).
Nigeria joined the United Nations on 7 October 1960, six days after independence — the 99th member state. The first Permanent Representative was Jaja Wachuku, who simultaneously held the Foreign Minister portfolio. The Mission has occupied premises in Turtle Bay since 1960; the current building is at 828 Second Avenue.
The Mission's institutional record includes: (i) leadership of the African Group in the General Assembly during the anti-apartheid years; (ii) chairmanship of the UN Special Committee against Apartheid (Joseph Garba, 1989–90); (iii) Nigeria's five non-permanent terms on the Security Council, in each of which the Mission served as the principal drafting delegation for West African and African crisis files (Liberia 1994–95, Côte d'Ivoire and Mali 2010–11, Boko Haram and South Sudan 2014–15); (iv) the negotiation of Nigeria's 1990s OPCW, CTBT, and ICC ratifications; and (v) hosting the annual ECOWAS Mission consultations on the margins of the General Assembly.
The Mission also handles Nigeria's UN funding contributions, peacekeeping personnel notifications, and the rotation of Nigerian staff into UN Secretariat appointments — a track that produced figures like Adebayo Adedeji, Ibrahim Gambari, and Amina Mohammed.
