Cape San Diego (Chinese: 三貂角; pinyin: Sāndiāojiǎo; Pe̍h-ōe-jī: Sam-tiau-kak) is a cape located in Gongliao District, New Taipei City, Taiwan. The cape is the easternmost point of the main Taiwan island, and also the easternmost cape of Taiwan. On 5 May 1626, a Spanish fleet reached the northeast tip of Taiwan and named the native village of Caquiunauan (present-day Fulong Village) as San Diego. Later this name was extended to the nearby cape.
