The Secretary General of the Union of South American Nations is the legal representative of the Secretariat of the Union of South American Nations (USAN).


The position was established by the UNASUR Constitutive Treaty and the first Secretary General was designated on 4 May 2010.


The Secretary General of UNASUR is proposed by the Foreign Ministers council, and designated by the Heads of State and Government council[1] for a two-year term, renewable once.[2] A Secretary General cannot be of the same nationality in succession.[1]
