Euharamiyids were a clade of early mammals or mammal-like cynodonts from the Jurassic Period in China. The group is sometimes considered a sister group to Multituberculata, or part of an earlier divergence within the synapsid line.

Evolution
By studying Euharamiyida, Bi et al. (2014) came to the conclusion that mammals evolved during the late Triassic, with allotherians diverging into Euharamiyids and Multituberculates around 208 million years ago from a common Haramiyavia-like ancestor. However, more recent studies showcase that euharamiyidans are more basal Mammaliaformes, outside of crown-group Mammalia, rendering Allotheria obsolete.
