Ontocetus emmonsi is the type species of Ontocetus, an extinct walrus of the family Odobenidae that lived in the coastal waters of the southern North Sea and the southeastern United States between the Miocene and the Pleistocene. Joseph Leidy named it in 1859 from a single tusk-like tooth that Ebenezer Emmons collected from the early Pliocene Yorktown Formation of North Carolina. For many years the tooth was thought lost and the animal was treated as a sperm whale. After the holotype was rediscovered in the 1990s, a review in 2008 treated several names from Belgium, England and the United States as junior synonyms of this species.
