The hoatzin ( ) or hoactzin ( ) (Opisthocomus hoazin) is a species of tropical bird found in swamps, riparian forests, and mangroves of the Amazon and Orinoco Basins in South America. It is the only extant species in the genus Opisthocomus which is the only extant genus in the Opisthocomidae family under the order of Opisthocomiformes.

They are sometimes called "termites of the sea". Carl Linnaeus assigned the common name Teredo to the best-known genus of
