The Von der Decken's hornbill (Tockus deckeni), is a species of hornbill found in East Africa, especially to the east of the East African Rift, from Ethiopia south to Tanzania. It is found mainly in thorn scrub and similar arid habitats. The Jackson's hornbill is often treated as a subspecies of it. It was named after the German explorer Baron Karl Klaus von der Decken (1833–1865).
