The Luzon Peacock Swallowtail (Papilio chikae) 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.
