The name is from the Latin juncus (rush) and folium (a leaf), which refers to the narrow, relatively long phyllodes appearing rush-like. Acacia juncifolia may be confused with A. calamifolia which usually has a racemose inflorescence and a curved phyllode apex (T.M. Tame, Acacias of Southeast Australia, 1992).
