Wu Ting-fang (30 July 1842 – 23 June 1922) was a Chinese calligrapher, diplomat, lawyer, politician, and writer who served as Minister of Foreign Affairs and briefly as Acting Premier during the early years of the Republic of China. He supported the Xinhai Revolution of 1911 and negotiated on the revolutionaries' behalf in Shanghai. He served briefly in early 1912 as Minister of Justice for the Nanjing Provisional Government, where he argued strongly for an independent judiciary, based on his experience studying law and travelling overseas. After this brief posting, Wu became Minister of Foreign Affairs for the ROC. He served briefly in 1917 as Acting Premier of the Republic of China. He joined Sun Yat-sen's Constitutional Protection Movement and became a member of its governing committee. He advised Sun against becoming the "extraordinary president" but stuck with Sun after the election. He then served as Sun's foreign minister and as acting president when Sun was absent. He died shortly after Chen Jiongming rebelled against Sun in 1922.
