Shen Chang-huan (Chinese: 沈昌煥; pinyin: Shěn Chānghuàn; 16 October 1913 – 2 July 1998) was a Taiwanese politician and diplomat.

He is the longest-serving Minister of Foreign Affairs in Taiwan's history, in office for a cumulative total of over twelve years from 1960 to 1966 and from 1972 to 1978.

He was a member of the Kuomintang (Chinese Nationalist Party), and from 1945 to 1948 served as Chiang Kai-shek's private secretary.

[2] His strong anticommunist convictions, his determination not to deviate from the one China position in the ROC's diplomatic relations, and the high value he placed on maintaining as close relations as possible with the United States coincided closely with the views of his leader [Chiang Ching-kuo].

[2] Shen's wife was the oldest daughter of Japanese-born Hong Kong filmmaker Lai Man-wai.
