Eucalyptus tortilis is a species of mallet and a gimlet that is endemic to the southwest of Western Australia.

Eucalyptus tortilis is a mallet and a gimlet, that typically grows to a height of 5–10 m (16–33 ft), has fluted stems and does not form a lignotuber.

[2][3][4] Eucalyptus tortilis was first formally described in 1991 by Lawrie Johnson and Ken Hill in the journal Telopea from specimens collected east of Norseman in 1983.

Six of these, including E. tortilis have buds in groups of seven, the others being E. campaspe, the mallee E. effusa, E. jimberlanica, E. salubris, E. ravida and E. terebra.

[6] This gimlet is found on flats and rises between Kalgoorlie and Esperance in the Goldfields-Esperance region where it grows in calcareous loamy soils.
