Hsieh Chi-ta (Chinese: 謝啟大; pinyin: Xiè Qǐdà; born 10 February 1949) is a Taiwanese lawyer and former politician who served in the Legislative Yuan from 1993 to 2002.

[3][10] Soon after taking office, Hsieh unsuccessfully intervened in the capital punishment case of Liu Huan-jung, a Bamboo Union gang member who had killed five people and been placed on Taiwan's death row for seven years before his execution.

[17] Believing that smaller constituencies would prevent elected officials from accurately reflecting "mainstream public opinion", she opposed a 1998 proposal on electoral district reform.

[22] By her third term, Hsieh was routinely listed by TVBS Weekly Magazine, the Vision Information Internet Association, and the Social Lawmaking League as one of the best legislators.

[25][26][27][28] Shortly after the election, First Lady of the Republic of China Tseng Wen-hui sued Hsieh, Elmer Fung, and Tai Chi for defamation.

[5][31] In her third term, Hsieh opposed the continued operation of the Lungmen Nuclear Power Plant and criticized the Republic of China Navy for excessive spending.

[2][6] Upon her return to Taiwan in December 2003, Hsieh served a three-month jail sentence for incidents of defamation that had occurred in 2000 involving Tseng Wen-hui.
