Feicui Dam (traditional Chinese: 翡翠水壩; simplified Chinese: 翡翠水坝; pinyin: Fěicuì Shuǐbà; Pe̍h-ōe-jī: Húi-chhùi Chúi-pà) is a double curvature concrete arch dam on the Beishi River in Shiding District, New Taipei, Taiwan, forming Feicui Reservoir (翡翠水庫).

Public access is heavily restricted in order to protect water quality, which is among the highest of Taiwan's reservoirs.

[4] This dam site was considered favorable because of good soil and forest conditions of the upstream watershed; at the time human development consisted mainly of tea plantations.

The quality was much better than the watershed behind Shihmen Dam, the other major water source for greater Taipei, which has suffered crippling sediment issues due to deforestation.

[3] A forebay dam 33 metres (108 ft) high is located immediately downstream, to reduce erosion from floodwater releases.

The plant operates under a gross head of 89 metres (292 ft), and the annual power generation is 223 million kilowatt hours.

[3] The dam and reservoir are noted for the lack of public access, in order to protect the quality of the drinking water.

With the exception of maintenance workers and Taipei City officials, visitation to the dam itself requires a special appointment and must be accompanied by a certified guide.
