Eucalyptus paniculata, commonly known as grey ironbark,[2] is a species of tree that is endemic to New South Wales.

Eucalyptus paniculata is a tree that typically grows to a height of 30–50 m (98–164 ft) and forms a lignotuber.

The fruit is a woody, conical, hemispherical or cup-shaped capsule 4–8 mm (0.16–0.31 in) long and wide with the valves close to rim level.

[2][3][4][5] Eucalyptus paniculata was first formally described in 1797 by James Edward Smith in Transactions of the Linnean Society of London from material collected by David Burton at Port Jackson.

[6][7] The specific epithet (paniculata) is from the Latin word paniculatus meaning paniculate, referring to the arrangement of the flowers.
