Wu Hsing-kuo (Chinese: 吳興國; Pe̍h-ōe-jī: Ngô͘ Heng-kok) is a Taiwanese actor of the silver screen and theater, known for both his performance of complex movie roles as much as for his innovative adaptations of Western classics into traditional Peking Opera.

He was admitted with honors into the Theatre Department of Chinese Culture University in Taipei, trained under master Chou Cheng-jung (Zhou Zheng-rong) and became the leading dancer of Lin Hwai-min's Cloud Gate Dance Theater.

However, his teacher Chou Cheng-jung (Zhou Zheng-rong) considered him as a pretentious student who didn't focus on study and finally abandoned him in 1989.

In 1986, he and a group of enthusiastic friends founded the Contemporary Legend Theatre [zh] in Taipei, seeking to revitalize traditional Chinese theatre by adapting Western classical plays to the style and techniques of Peking Opera.

He crosses the fields of traditional opera, dance, modern theatre, cinema, and television.
