Dalongdong (Chinese: 大龍峒; pinyin: dàlóngdòng), or Toalongpong (Chinese: 大龍泵; Pe̍h-ōe-jī: Tōa-lông-pōng; and variants 大浪泵/大隆同), is an old town in historical Taipei located near the narrows of the confluence of the Keelung and Tamsui Rivers.
Although the history of the settlement likely preceded Dutch Formosa rule, its existence was first recorded as Pourompon (from the Basay language).
This gave rise to the names Paronpon (Chinese: 巴浪泵; Pe̍h-ōe-jī: Pa-lông-pōng), Daronpon (大龍泵; Toā-lông-pōng)[1] and other variants, when the area came under Qing dynasty rule.
The name was once again changed (大隆同; Toā-liông-tông) in 1802 (7th year of Jiaqing Emperor), by settlers from Tong'an District in Xiamen.
The name finally settled in its present form (大龍峒) during the reign of the Daoguang Emperor (1820-1850) when further settlement occurred in the area.
