Zhang Qianfan (张千帆; born January 1964) is a constitutional law professor at Peking University Law School,[1] and an activist who advocates constitutionalism in China and has called for China's general political and judicial reform.

He earned a CUSPEA scholarship to attend Carnegie-Mellon University, Pittsburgh, PA, where he received a PhD degree in biophysics in 1989.

In 1995, he was awarded a scholarship to attend the University of Texas at Austin and received a PhD degree in Governmental Theory in 1999.

[4] In February 2019, his textbook, Study of Constitutional Law: Principles and Applications was withdrawn from book stores and university teaching materials in China, as part of a nationwide check on constitutional law textbooks launched by the Ministry of Education earlier that year.

He also noted that this development represented a "retreat" from China's own constitution, of which Article 35 guarantees freedoms of speech and publication.
