Opabinia [oh-puh-bin-ee-uh] is an extinct animal found in Cambrian fossil deposits. Its sole species, Opabinia regalis, is known from the Middle Cambrian Burgess Shale of British Columbia. The discoverer of Opabinia, American paleontologist, Charles Doolittle Walcott, named it after a local mountain, Opabin Peak in the Canadian Rockies.

Thirty specimens of Opabinia are known and each ranges in size from 40-70 mm. The most intriguing feature of Opabinia are its five eyes found on the dorsal surface of the head.
