Tsung-Tung Chang (Chinese: 張聰東; pinyin: Zhāng Cōngdōng; 1930–2000) was a Taiwanese-German economist and Sinologist.
In 1967, Otto Karow, the chair for East Asian philology and cultural studies at the Johann Wolfgang Goethe University, hired Chang as a Chinese lecturer.
Here Chang began to study Chinese oracle bone inscriptions, which he submitted to Karow in 1970 as a dissertation.
When the professorship for Sinology was re-established in 1973 as part of the reorganization of the university, Chang was appointed professor.
With a series of lectures, exhibitions and concerts, he succeeded in building on the legacy of his predecessors Richard Wilhelm and Erwin Rousselle.
