Acacia xanthina, commonly known as white stemmed wattle, is a coastal shrub or small tree in the family Fabaceae. Endemic to Western Australia, it occurs on coastal limestone between Fremantle and Shark Bay. Acacia xanthina was first collected in 1839 by James Drummond, and described by George Bentham in 1842. The specific name comes from the Greek xanthos, meaning yellow, and refers to the flowers.
