Acer acuminatum is an Asian species of maple native to the Himalayas and neighboring mountains in Tibet, Kashmir, northern India, Nepal, and Pakistan.

Acer acuminatum is a multi-stemmed tree up to 10 meters tall. It is dioecious, meaning that male and female flowers form on separate plants. Leaves are up to 12 across, each with 3 or 5 lobes. The apexes of its leaves are both caudate and acuminate. Its infructescence ranges from 12 to 20 centimeters long.
