Liu Chao-shiuan (Chinese: 劉兆玄; pinyin: Liú Zhàoxuán; born 10 May 1943) is a Taiwanese chemist and politician.

Liu is also an author, and, together with two of his brothers, has published novels of ancient Chinese rovers practicing martial arts under a pen name called "Shangguan Ding" (上官鼎).

In April 2008, Liu was asked by current President Ma Ying-jeou to serve as the Premier of the Republic of China.

Liu and his Cabinet resigned en masse on 10 September 2009, with Wu Den-yih succeeding the post of Premiership.

Liu had suffered mounting criticism over the aftermath of Typhoon Morakot, and had initially tendered his resignation to President Ma in mid-August.
