Zacharias Joachim Cleve (December 3, 1820 – January 20, 1900) was a Finnish pedagogue and philosopher.
He served as an assistant professor of education and didactics (kasvatus- ja opetusoppi) at the University of Helsinki from 1862 to 1882.
Cleve was born in Rantasalmi to vicar Joachim Adolf and Juliana Aminoff.
In 1854 he wrote a book on pedagogy Försök till lärobok i psykologi.
According to him this principled autonomy enabled it to be useful without being an instrument for organizing power or managing mindsets.
