Cormocephalus coynei is a species of centipede found on the uninhabited Phillip and Nepean islands to the south of Norfolk Island.

[3] The species was observed on Phillip Island in 1792,[2] but was not formally described until 1984.

[1][4] It can grow up to 23.5 cm,[5] and is reddish brown and orange in colour.

The Phillip Island centipede is known for its habit of preying on vertebrates including geckos, skinks, black-winged petrel (Pterodroma nigripennis) nestlings, and fish, as well as other small arthropods.

It is theorized that the centipede was able to enter this ecological niche due to the absence of endemic mammalian predators on the island.
