Yunnanodon ("Yunnan tooth", from China's Yunnan province where it was discovered, and the Greek don(ti) (δόντι) meaning "tooth") was a genus of non-mammalian therapsid that lived in China during the Sinemurian stage of the Early Jurassic period. Its specific name brevirostre is Latin for "short-beaked" (brevis ("short") + rostrum ("beak")).
