Eucalyptus proxima is a mallee that typically grows to a height of 3 m (9.8 ft) and forms a lignotuber.

The flower buds are arranged in leaf axils in groups of seven on a slightly flattened, down-turned, unbranched peduncle 12–22 mm (0.47–0.87 in) long, the individual buds sessile or on thick pedicels 1–4 mm (0.039–0.157 in) long.

[2][3][4] Eucalyptus proxima was first formally described in 2005 by Dean Nicolle and Ian Brooker from a specimen they collected near Jerdacuttup in 2002.

[2][3][4] This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
