Zanthoxylum yuanjiangensis (Chinese: 元江花椒, Yuanjiang prickly ash) is a woody plant in the Rutaceae.

The leaves consist of 7–15 somewhat leathery leaflets; these range from alternate to nearly opposite and are elliptical, ovate or rarely obovate.

Inflorescences are terminal or axillary cymes near the top, 26 cm long, with many flowers, each consisting of 4 sepals and petals.

The infructescence is 12 cm wide, semicircular umbrella-shaped; the lamina is about 6 mm in diameter and dark brown to black after drying; the oil gland is not obvious, and the top has a short awn tip.

It can be found in hilly shrublands at an altitude of 450–600 meters or in humid secondary forests on both sides of the valley.
