Xenodontolacerta (meaning "lizard with strange teeth") is an extinct genus of polyglyphanodontian lizard from the Late Cretaceous (Coniacian–Campanian ages) Hekou Formation of China. The genus contains a single species, Xenodontolacerta fangi, known from a partial skull and mandible. Its teeth are uniquely heterodont, more similar to polyglyphanodontians from North America than those in Asia. This unique tooth morphology suggests Xenodontolacerta was likely omnivorous, contrasting with its herbivorous contemporaries.
