Tseng Wen-hui (Chinese: 曾文惠; pinyin: Zēng Wénhuì; Pe̍h-ōe-jī: Chan Bûn-hūi; (born 31 March 1926) is a Taiwanese public figure, First Lady of the Republic of China (Taiwan) from 1988 to 2000, and widow of former Taiwanese President Lee Teng-hui.

[3] Tseng was born on 31 March 1926 in Sanshi Village, Taihoku Prefecture, now known as present-day New Taipei City, Taiwan.

Tseng married Lee on 9 February 1949, when he was a teaching assistant in the Faculty of Agriculture and Economics at National Taiwan University.

However, she became the subject of controversy in 2000 when New Party politicians Elmer Fung, Hsieh Chi-ta, and Tai Chi accused her of attempting to flee to New York City with a suitcase containing NT$85 million.

In response, she filed a defamation suit against them on 29 March 2000, making her the only first lady in Taiwan's history to become involved in a lawsuit.
