Christian Wolff (less correctly Wolf; also known as Wolfius; ennobled as: Christian Freiherr von Wolff; 24 January 1679 – 9 April 1754) is a German philosopher.

He is the most eminent German philosopher between Leibniz and Kant.

His main achievement is a complete oeuvre on almost every scholarly subject of his time, displayed and unfolded according to his demonstrative-deductive, mathematical method, which perhaps represents the peak of Enlightenment rationality in Germany.

Wolff is also the creator of German as the language of scholarly instruction and research, although he also writes in Latin, so that an international audience can, and does, read him.

A founding father of, among other fields, economics and public administration as academic disciplines, he concentrates especially in these fields, giving advice on practical matters to people in government, and stressing the professional nature of university education.
