lansdowneana (Little Desert) Eucalyptus walshii is a small, slender, pole-like tree that is endemic to Victoria, Australia.

Eucalyptus walshii is a tree that typically grows to a height of 4–9 m (13–30 ft) and forms a lignotuber.

Young plants and coppice regrowth have elliptical to narrow lance-shaped leaves that are about 100 m (330 ft) long and 23 mm (0.91 in) wide.

[2][3] Eucalyptus walshii was first formally described in 2004 by Kevin James Rule in the journal Muelleria from specimens collected near Broughton's Waterhole in the Little Desert National Park in 2002.

[3] This eucalypt is only known from a single population growing in mallee woodland on a low hill near the type location.
