Ms Bachelet, who was hailed by the UN Secretary General, Antonio Guterres as a "pioneer", said she was "deeply humbled and honored".
“Michelle Bachelet brings unique experience to the United Nations and to all of us, and is strongly committed to keeping human rights at the forefront of the work of the United Nations,” Mr Guterres told reporters following the announcement of her appointment.
“She has my full confidence and support, and I ask all Member States and our partners to extend to her their support," he added.
