Su Tseng-chang
Taiwanese politician

Su Tseng-chang (Chinese: 蘇貞昌; pinyin: Sū Zhēnchāng; Pe̍h-ōe-jī: So͘ Cheng-chhiong; born 28 July 1947) is a Taiwanese politician who served as the premier of the Republic of China from 2006 to 2007 and again from 2019 to 2023. He was the chairman of the Democratic Progressive Party in 2005 and from 2012 to 2014. Su served as Chief of Staff to President Chen Shui-bian in 2004. He is currently the longest-serving Democratic Progressive premier in history.
Su actively campaigned for the DPP presidential nomination in 2008, but finished second to Frank Hsieh. Su eventually teamed with Hsieh as the vice presidential nominee; the DPP lost to the Kuomintang ticket of Ma Ying-jeou and Vincent Siew. Su ran for Taipei City Mayor in November 2010, but lost to the incumbent Hau Lung-pin by a 12-point margin. Su campaigned for the 2012 presidential candidacy of the DPP in 2011, but lost to Tsai Ing-wen by a very narrow margin. Following the loss of Tsai to Ma Ying-jeou, Su was elected to succeed Tsai as DPP chairman in 2012.
During the Chen administration, Su, along with politicians Annette Lu, Frank Hsieh and Yu Shyi-kun, are collectively known as the "Big Four of the Democratic Progressive Party".

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q551904. VIAF identifies the subject as 23621030. The Library of Congress control number is n86070296. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 2006, 2007 and 2019.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
