Tubonasus (meaning “tube nose”) is an extinct monospecific genus of long-snouted arthrodire placoderm from the Early Frasnian stage of the Late Devonian period, found at the Gogo Formation of Kimberley, Western Australia.

Tubonasus is interpreted as a pelagic pursuit predator, and had the ability of swallowing prey whole. Like other camuropiscids, it has an elongated rostrum, streamlined body, and narrow infragnathals.
