Wanosuchus ("Wangjiang County crocodile") is an extinct genus of sebecosuchian mesoeucrocodylian known from Paleocene-age rocks of southern Anhui, China.

The bone lacks an external mandibular fenestra and has thirteen teeth, the longest of which are the fourth and eleventh.

It was collected between 1970 and 1972 by Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) personnel; the exact location and rock unit that produced the bone are uncertain.

Zhang classified Wanosuchus under its own family within Sebecosuchia, Wanosuchidae.

[1] It shares some characteristics with Doratodon, a crocodyliform from the Late Cretaceous of Europe.
