The Taiwan Statebuilding Party (TSP; Chinese: 台灣基進; pinyin: Táiwān Jījìn; Pe̍h-ōe-jī: Tâi-oân Ki-chìn) is a political party in the Republic of China (Taiwan). The party was established in 2016 as Taiwan Radical Wings.^[4] The party is considered a rather close ally of the DPP,^[10] while fighting to replace opposition parties whom TSP unilaterally claims as “not loyal to Taiwan”,^[11] such as Kuomintang and TPP. In Taiwan’s 2024 Legislative Election, TSP failed to gain any seat in the Legislative Yuan and lost its status as a national political party.

As of 2018, the chairperson was Chen Yi-chi.^[12]

In the 2020 legislative elections in Taiwan, the party won one seat, with Chen Po-wei becoming its first member of the Legislative Yuan.^[13]

In October 2021, Chen became the first member of the Legislative Yuan to be successfully recalled, ending his term less than two years into office.^[14] Votes for Chen's recall numbered 77,899, against 73,433 opposing his recall. Votes supporting the recall topped 25% of the eligible electorate (73,744), with 51.72 percent voter turnout.^[15] Per Article 92 of the Civil Servants Election and Recall Act [zh], Chen will be ineligible to run for the Legislative Yuan in Taichung's second district for the next four years.^[16] On 28 October 2021, he was officially dismissed from the Legislative Yuan.^[17]
