The Taiwan blue magpie (Urocissa caerulea), also called the Taiwan magpie, Formosan blue magpie (Chinese: 臺灣藍鵲; pinyin: Táiwān lán què), or the "long-tailed mountain lady" (Chinese: 長尾山娘; pinyin: Chángwěi shānniáng; Taiwanese Hokkien: Tn̂g-boé soaⁿ-niû), is a species of bird of the crow family. It is endemic to Taiwan.
The Taiwan blue magpie was collected by Robert Swinhoe and described by John Gould. Swinhoe called it the "Long-tailed Mountain-Nymph". The Taiwan blue magpie is sometimes placed in the genus Cissa. It forms a superspecies with the yellow-billed blue magpie (Urocissa flavirostris) and the red-billed blue magpie (Urocissa erythroryncha). The species is monotypic.
