孔雀蛺蝶（学名：Aglais io）是一種色彩鮮艷的蝴蝶，分佈在歐洲及東至日本的亞洲溫帶。它們是孔雀蛺蝶屬下的唯一物種，學名取自希臘神話中的伊那科斯及其女兒伊俄。它們很易與非釉蛺蝶屬混淆，但兩者並非近親。它們很多會留在生活的地方，在建築物或樹中過冬。故它們會在初春時出現。

Encyclopedic overview

Aglais io, the European peacock, or the peacock butterfly, is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. The peacock butterfly is resident in much of its range, often wintering in buildings or trees. It therefore often appears quite early in spring.

The peacock butterfly has figured in research in which the role of eyespots as an anti-predator mechanism has been investigated. The peacock is expanding its range and is not known to be threatened.
