Ng Chiau-tong (Chinese: 黃昭堂; pinyin: Huáng Zhāotáng; Pe̍h-ōe-jī: N̂g Chiau-tông) (1932 – November 17, 2011) was a Taiwanese pro-independence activist who served as the Chairman of the World United Formosans for Independence (WUFI) until his death in 2011.
Ng was born in Tainan Prefecture, Japanese Taiwan (modern-day Tainan, Taiwan) in 1932. He graduated from National Taiwan University in 1958 before moving to Japan, where he obtained a master's degree from Tokyo Imperial University, now the University of Tokyo. He participated in his first pro-Taiwanese independence demonstration while in Tokyo while studying for his master's degree.
In 1960, Ng established the Taiwan Youth Society in Tokyo, which later became a branch of the World United Formosans for Independence in Japan. His pro-independence activism in Japan lead to a blacklist by the Kuomintang, which governed the Republic of China (Taiwan) at the time. The Kuomintang banned Ng from returning to Taiwan.
Ng was finally permitted to return to Taiwan from exile in 1992 by the Lee Teng-hui administration. He became Chairman of the World United Formosans for Independence in 1995 and held the position until his death in 2011. He served as a presidential adviser to former DPP President Chen Shui-bian. Ng helped organize the February 28, 2004 hand-in-hand rally, in which one million Taiwanese joined in a human chain along the west coast of Taiwan from Keelung to Eluanbi, which was seen as a key event in President Chen Shui-bian's 2004 re-election campaign.
