Acacia pycnantha, commonly known as the golden wattle, is a tree of the family Fabaceae native to south eastern Australia. It grows to a height of 8 m and has phyllodes instead of true leaves. Sickle-shaped, these are between 9 and 15 cm long, and 1–3.5 cm wide. The profuse fragrant, golden flowers appear in late winter and spring, followed by long seed pods.
