Wu Zhen ( 11th century), courtesy name Tingzhen, was a historian of the Chinese Northern Song dynasty. He is known for writing two books enumerating mistakes found in the New Book of Tang and Historical Records of the Five Dynasties, both of which were authored by Ouyang Xiu (Ouyang had several co-authors with New Book of Tang). As pointed out in the 18th-century Siku Quanshu, Wu Zhen was "inclined to criticise for the sake of criticism".
Although he apparently wrote other works (including a monograph on the Five Dynasties period Later Liang dynasty), Wu Zhen's only 2 surviving books are:
Both were published after Ouyang Xiu's death in 1072. In the first book's preface, Wu Zhen blasted the New Book of Tang as the worst official history book ever written.
