The Secretary - General serves as the chief administrative officer of the United Nations . The role of the United Nations Secretariat, and of the Secretary - General in particular, is laid out by Chapter XV (Articles 97 to 101) of the United Nations Charter . </P> <P> As of 2017, the Secretary - General is António Guterres, appointed by the General Assembly on 13 October 2016 . </P> <P> The Secretary - General was envisioned by U.S. President Franklin D. Roosevelt as a "world moderator", but the vague definition provided by the UN Charter left much room for interpretation by those who would later occupy the position . According to the UN website, their roles are further defined as "diplomat and advocate, civil servant, and CEO". Nevertheless, this more abstract description has not prevented the office holders from speaking out and playing important roles on global issues to various degrees . Article 97 under Chapter XV of the United Nations Charter states that the Secretary - General shall be the "chief administrative officer" of the Organization, but does not dictate their specific obligations . </P>
