"Green Terror" () is a political term used to characterize and criticize purported "authoritarian-like" actions of the Democratic Progressive Party (DPP) or the pan-Green camp. It is used by the DPP's opponents in Taiwan (mainly the pan-Blue camp and the Taiwan People's Party), but is also sometimes used by the Chinese Communist Party (CCP) and local CCP supporters. The term is a combination the DPP's party color and "White Terror", a reference to political repression under the Kuomintang's rule by martial law.
Since 2014, the Ma Ying-jeou government has attempted to reduce Taiwanization and strengthen the identity of the 'Republic of China' in high school history subjects. This has intensified into a political debate, with criticism from pan-Green camps, including the DPP, which values the 'Taiwanese' identity over the identity of the 'Republic of China'. After asserting that the DPP's view on the deletion of the "White Terror" from the new syllabus was a form of de-Taiwanization, , a politician with the Chinese ultra-nationalist New Party, said that the DPP's approach was the "Green Terror".
Following the arrest of Ko Wen-je, the chairman of the Taiwan People's Party (TPP), Huang Kuo-chang blamed the arrest on Green Terror.
When the 2024 South Korean martial law crisis (caused by Yoon Suk Yeol, the then far-right anti-communist South Korea's president) broke out, the DPP Legislative Caucus posted an article on Threads, claiming that the declaration of martial law was a legitimate effort to protect free constitutional democracy in South Korea. This led to the DPP being criticized by South Korean netizens, Chang Chi-kai and some Chinese/Taiwanese media dubbed it the "Green Terror".
