Ketagalan Boulevard (Chinese: 凱達格蘭大道; pinyin: Kǎidágélán Dàdào) is an arterial road in Zhongzheng District in Taipei, Taiwan, between the Presidential Building and the East Gate (東門). It is 400 metres (1,300 ft) long and has a total of ten lanes in both directions with no median.
The former name of this street is Chieh-shou Road (traditional Chinese: 介壽路; simplified Chinese: 介寿路; pinyin: Jièshòu Lù; Wade–Giles: Chieh-shou lu), Chieh-shou (介壽) meaning "Long live Chiang Kai-shek". On May 19, 1989 a pro-democracy activist named Chan I-hua performed self-immolation to protest the blocking of funeral procession of fellow activist Cheng Nan-jung. On 21 March 1996, when Chen Shui-bian was the mayor of Taipei, Chieh-shou Road was renamed Ketagalan Boulevard and the surrounding square was renamed Ketagalan Square in honor of the Ketagalan Taiwanese aborigines originally living in the Taipei area. However, Ketagalan Boulevard has been given other levels of political meaning and has even become the protesting holy land of opposing political parties.
