The Toucan Barbet, Semnornis ramphastinus, is a distinctive Neotropical bird.

In the past, it has been grouped with the other barbets in the Capitonidae. However, DNA studies have confirmed that this arrangement is paraphyletic; the New World barbets are more closely related to the toucans than they are to the Old World barbets. As a result, the barbet lineages are now considered to be distinct families, and the Toucan Barbet, together with the Prong-billed Barbet, is now placed into a separate family, Semnornithidae.

The Toucan Barbet is unusual amongst frugiverous birds in that it breeds cooperatively, with several helpers aiding the dominant breeding pair with incubation and raising the young.
