Ficus rubiginosa, commonly known as the rusty- or Port Jackson fig (damun in the Dharug language) is a species of flowering plant native to eastern Australia in the genus Ficus. Beginning as a seedling that grows on other plants (hemiepiphyte) or rocks (lithophyte), F. rubiginosa matures into a tree 30 m (100 ft) high and nearly as wide with a yellow-brown buttressed trunk. The leaves are oval and glossy green and measure from 4 to 19.3 cm (1 1⁄2–7 1⁄2 in) long and 1.25 to 13.2 cm (1⁄2–5 1⁄4 in) wide.
