Eucalyptus fibrosa, commonly known as the red ironbark or broad-leaved red ironbark, is a type of ironbark tree found in eastern Australia, mainly in Queensland and New South Wales. This plant is in family Myrtaceae.

It was originally described by Victorian state botanist Ferdinand von Mueller in 1859 from a collection from the Brisbane River.

The blue-leaved ironbark (Eucalyptus nubila) was formerly considered a subspecies of this species.

The tree grows to a height of about 35 meters (115 feet) and a spread of around 10 m (33 ft) The trunk has deeply furrowed dark gray bark. The alternately arranged lanceolate leaves are dark grey-green and broader than other ironbarks, measuring 12–18 cm (4.7–7.1 in) long and 2.5–5 cm (0.98–1.97 in) wide. They are on petioles 1.5–2.7 cm (0.59–1.06 in) long. The flowers are creamy white. The dense, strong wood is valued for lumber. The sap, locally called "kino," was used by natives to keep fish lines from fraying and by the early settlers for ink.
