Eucalyptus nutans, commonly known as red-flowered moort,[1] is a species of mallet that is endemic to a small area near the south coast of Western Australia.

Eucalyptus nutans is a single-stemmed, small tree that typically grows to a height of 4–10 m (13–33 ft) but does not form a lignotuber.

[1][3][4][5] Eucalyptus nutans was first formally described in 1863 by Ferdinand von Mueller from specimens collected by George Maxwell near Bremer Bay.

This mallet is only known from a single location near Bremer Bay where is grows in a more or less pure stand with Acacia glaucoptera, A. cyclops, Hakea laurina, Eucalyptus phenax, E. occidentalis, Rhadinothamnus rudis and species of Lepidosperma and Astroloma also present.

It is rare in nature but is known as cultivated specimens in gravel pits near Albany and in Kings Park, grown from the seed collected between 1968 and 1989.
