Rubus cockburnianus (white-stemmed bramble) is a species of flowering plant in the family Rosaceae. It is endemic to China.

This bramble is a shrub growing up to 3 meters tall. The smaller branches are brown or reddish, hairless, waxy, and armed sparsely with prickles. The leaves are divided into several serrated leaflets which are hairless or slightly hairy on the upper surfaces and woolly-haired underneath. Inflorescences occur in the axils and at the ends of branches. The pink flowers are about one centimeter wide and have many stamens in their centers. The purple-black aggregate fruit is under a centimeter long.
