Georg Christian Benedict Ackermann (3 March 1763 – 8 April 1833) was a German theologian and teacher. He was born in Vier (now part of Boizenburg) upon the river Elbe. He visited school in Schwerin in Mecklenburg, then in 1782 the University of Göttingen in Hanover to study theology. Ackermann was engaged in ameliorating the public school system, orphanages, and poor houses. Aside from his sermons, he published in the Monatsschrift von Mecklenburg, in Schiller's Patriotisches Archiv der Herzogtümer Mecklenburg and in the Schweriner freimütiges Abendblatt.
