Ketagalan or Ketangalan (traditional Chinese: 凱達格蘭族; simplified Chinese: 凯达格兰族; pinyin: Kǎidágélán Zú) are a Taiwanese aboriginal people originating in what is now the Taipei Basin.[1] Their language has now become extinct.
On 21 March 1996, the road in front of the Presidential Office Building was renamed from "Long Live Chiang Kai-shek" Road (介壽路) to Ketagalan Boulevard (凱達格蘭大道) by then-mayor of Taipei City, Chen Shui-bian, to commemorate the people. Traffic signs banning motorcycles and bicycles from that road were abolished at the same time.
Beitou District in Taipei City houses the Ketagalan Culture Center, a cultural center about the Ketagalan people.
