Lee Ta-hai (simplified Chinese: 李达海; traditional Chinese: 李達海; pinyin: Lǐ Dáhǎi; 6 March 1919 – 13 November 1994)[1] was a Taiwanese politician and businessman.

A former executive of the Chinese Petroleum Corporation, Lee was Minister of Economic Affairs under President Chiang Ching-kuo and continued to advise the Republic of China government under Chiang's successor, Lee Teng-hui.

The beginning of Lee's term was marked by growing pressure from the United States to reduce tariffs and trade barriers amidst a growing trade deficit in the U.S.[2] As head of the ROC's economic policy, Lee presided over the gradual liberalization that characterized the later years of Chiang Ching-kuo's administration while balancing relations with the U.S.[3] His refusal to allow the NT dollar to appreciate against the U.S. dollar, however, caused further friction with the American government and raised the threat of trade sanctions in 1987.

[4] Although Chiang Ching-kuo died in January 1988, Lee continued to serve as Minister for another six months, after which he declined to pursue a seat in the Kuomintang Central Council.

He continued to assist the KMT administration under Lee Teng-hui as National Policy Advisor.
