Arboroharamiya is an extinct genus of early mammal (or possibly a non-mammalian mammaliaform) from the Middle Jurassic Tiaojishan Formation of Inner Mongolia, China. Arboroharamiya belongs to a group of mammaliaforms called Haramiyida. The type species Arboroharamiya jenkinsi was described in the journal Nature in 2013 alongside a description of the closely related haramiyidan Megaconus. Unlike Megaconus, which is thought to have been ground-dwelling, Arboroharamiya was arboreal. It has a long tail that might have been prehensile, and very long fingers. Based on the shape of its teeth, Arboroharamiya might have been an omnivore or a seed eater.
