Noteosuchus is an extinct genus of basal rhynchosaur known from the earliest Triassic deposits of Eastern Cape Province, South Africa.

The generic name erected by Broom (1925) is a compound, meaning "Not Eosuchus",[1] while "Eosuchus" is derived from the name of Eos, the goddess of the dawn in Greek mythology, and suchus, Latinized from the Greek souchos, an Egyptian crocodile god, thus meaning "dawn crocodile".

[2] Noteosuchus is known solely from the holotype AM 3591, a well-preserved partial postcranial skeleton, missing the head, which is currently housed at the Albany Museum in South Africa.

[6] However, Ezcurra, Scheyer and Butler (2014) noted that this synonymy was based only on generalized rhynchosaur plesiomorphic similarities rather than autapomorphies.

Additionally, their phylogenetic analysis recovered Noteosuchus and Mesosuchus in a polytomy with Howesia browni, a result which is inconsistent with such synonymy.
