Eucalyptus ophitica, commonly known as the serpentine ironbark,[2] is a species of small ironbark tree that is endemic to a small area of northern New South Wales.

Eucalyptus ophitica is a tree that typically grows to a height of 10–15 m (33–49 ft) and forms a lignotuber.

The flower buds are arranged in leaf axils in groups of seven on a peduncle 4–10 mm (0.16–0.39 in) long, the individual buds on pedicels 3–8 mm (0.12–0.31 in) long.

The flowers are white and the fruit is a woody, cup-shaped, conical or hemispherical capsule 4–6 mm (0.16–0.24 in) long and 5–7 mm (0.20–0.28 in) wide with the valves protruding above the rim.

[2][3][4] Eucalyptus ophitica was first formally described in 1990 by Lawrie Johnson and Ken Hill in the journal Telopea from specimens collected near Baryulgil in 1984.
