Taiwan Sugar Corporation (TSC; Chinese: 台灣糖業股份有限公司; Pe̍h-ōe-jī: Tâi-oân Thn̂g-gia̍p Kó͘-hūn Iú-hān Kong-si; pinyin: Táiwān Tángyè Gōngsī) or Taisugar (Chinese: 台糖; Pe̍h-ōe-jī: Tâi-thn̂g; pinyin: Táitáng) is a state-run enterprise of Taiwan, with headquarters in Tainan City.

The corporation was established on 1 May 1946 by the Nationalist government after the handover of Taiwan from Japan to Republican China, by merging all of the sugar companies (Dai-Nihon, Taiwan, Meiji, and Ensuiko Sugar Company) during the Japanese era in Taiwan. In the 1950s and 1960s, sugar was one of the major exports of Taiwan; the corporation remains a major land owner today.^{[citation needed]}

Taiwan's sugar trade, which flourished for almost 400 years, is now a sunset industry. The Taiwan Sugar Corporation has diversified its business into tourism, floriculture, biotechnology, and retailing. It also operates a chain of gas stations and invests in Taiwan High Speed Rail.^{[citation needed]} They also have a number of significant overseas investments. In 2020 Taiwan Sugar Corporation announced plans to close its largest pig farm in Vietnam and instead invest NT$10.7 billion (US$369 million) in remodeling and improving their pig farms in Taiwan.^[1]
