Chang Ya-juo (traditional Chinese: 章亞若; simplified Chinese: 章亚若; pinyin: Zhāng Yāruò; 1913–1942) was the mistress of Chiang Ching-kuo and bore two sons for him, Winston Chang and John Chiang in 1941. The twins took their mother's surname as they were born out of wedlock. Chang died under mysterious circumstances in 1942 and the twins were raised by Chang's brother.
