Papilio chikae, the Luzon peacock swallowtail, is a species of butterfly in the family Papilionidae. It is endemic to the Philippines. It has two subspecies, with P. c. chikae from Luzon and P. c. hermeli (Nuyda, 1992) from Mindoro. The latter was originally described as a separate species, but it resembles the nominate subspecies and there are no significant differences in their genitalia, leading recent authorities to treat them as subspecies of a single species.
Their forewings are black with pale blue veins, while their hind wings are black with turquoise and red edges.
