Acer sinense is a species of flowering plant in the maple genus Acer, native to southeast and south-central China.[2] A small (typically 3 to 5 m tall) tree rarely reaching 15 m, it prefers to grow in forested valleys 500 to 2500 m above sea level.[3]

It is a highly morphologically variable species, leading to some taxonomic confusion. Some authorities consider it to be a subspecies of Campbell's maple, Acer campbellii subsp. sinense, but this is incorrect; it is in its own species complex.[4] Good traits to distinguish it from members of the Acer wilsonii species complex are that its inflorescence is a compound corymbose panicle with 60 to 70 flowers, with pedicels that are 5 to 6 mm long, its ovaries are pillose, appearing white, and its nutlet is nearly glabrous, and convex, without any veins.[4]
