Eucalyptus parramattensis, commonly known as the Parramatta red gum or drooping red gum,[2] is a species of small to medium-sized tree that is endemic to eastern New South Wales.

Eucalyptus parramattensis is a tree that typically grows to a height of 15–18 m (49–59 ft) and forms a lignotuber.

The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 5–10 mm (0.20–0.39 in) long, the individual buds on pedicels 3–5 mm (0.12–0.20 in) long.

[2][3][4][5] Eucalyptus parramattensis was first formally described in 1913 by Edwin Cuthbert Hall in Proceedings of the Linnean Society of New South Wales from material collected by Richard Thomas Baker.

[6][7] Two subspecies and one variety are accepted by the Australian Plant Census: Parramatta red gum grows in woodland, on flat and gently sloping country, often in wet sites on sandy soils.
