Acer yangbiense is a species of maple with a very restricted distribution in Yunnan, China, only known from around ten specimens from a single locality on the western slope of Mount Cangshan in Yangbi County. Acer yangbiense is a deciduous tree up to 20 metres (66 ft) in height with noticeably pubescent new branchlets. The leaves are five-lobed and large, up to 20 cm long and 25 cm across, again with clear pubescence on the veins on the underside of the leaves.
