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 village in historical Taipei located near the narrows of the confluence of the Keelung and Tamsui Rivers. The district has since been merged with the newer Twatutia district in the south during the Qing dynasty to form Datong District.
The village, officially created in 1853 (3rd year of the Xianfeng Emperor), covered the area extending from the Chen Teacher's abode (陳悅記祖宅) and beyond the area of sishisikan (四十四坎) and the Taipei Confucius Temple. During Japanese rule, the villages of Twatutia, Toalongpong, and Bangka were combined with the walled city of Taipeh (in present-day Zhongzheng District) and incorporated into present-day Taipei city. Although this district now exists only historically, its name still officially remains in the Dalongdong Baoan Temple and on bus numbers 303 and 669 of the Taipei bus system.
