Oxynoticeras is an extinct genus of ammonite from the Early Jurassic of Europe and North America. This genus is characterized by its smooth shell, with almost invisible undulations on the flank, and a sharp keel.

Synonym Oxynotoceras was created by Buckman as misspelling.

Fossils belonging to this genus were found in Europe, Morocco, Asia, Canada, USA and South America.
