Oxynoticeratidae is a family of true ammonites (order Ammonitida) included in the superfamily Psiloceratoidea.

Oxynoticeratids have a broad, worldwide distribution but a narrow stratigraphic one, being known only from the Upper Sinemurian and Lower Pliensbachian,[2][3] during which their shells changed little in form.
