Chuang Ming-yao (; 16 November 1929 - 6 January 2002) was a Taiwanese admiral, diplomat, and politician.
Chuang served as the Vice Minister of National Defense under Chen Li-an and was named commander of the Republic of China Navy in 1992. He stepped down from that position in 1994 as a result of the La Fayette-class frigate scandal. Two years later, Chuang was selected to lead the Taipei Economic and Cultural Representative Office in Japan. In May 2000, he was named the Secretary-General of the National Security Council.[1]
He died in 2002 of liver cancer at the age of 72, while being treated at Taipei Veterans General Hospital.[1]
