Chang Chun-hsiung (Chinese: 張俊雄; pinyin: Zhāng Jùnxióng; Pe̍h-ōe-jī: Tiuⁿ Chùn-hiông; born 23 March 1938) is a Taiwanese politician and lawyer who had served as the prime minister of Taiwan (officially Premier of the Executive Yuan) from 2000 to 2002 and 2007 to 2008, both under Chen Shui-bian's presidency.

His appointment by then-President Chen in 2000 marked the first time a Democratic Progressive Party (DPP) member occupied the premiership.

Chang was born in 1938 in the city of Kagi (present-day Chiayi) when Taiwan (then Formosa) was still a colony of Japan.

In 1994, Chang stood as the Democratic Progressive Party candidate to run for the mayor of Kaohsiung, but was defeated by the Kuomintang incumbent Wu Den-yih.

[6] Chang maintained a long-term marriage-like relationship with a paramour while remaining legally married to his first wife, Hsu Jui-ying.
