Eucalyptus nitida, commonly known as the Smithton peppermint,[3] is a species of tree or mallee that is endemic to Tasmania.

[3][4] Eucalyptus nitida was first formally described in 1856 by Joseph Dalton Hooker in his book, The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror.

[5][6] The specific epithet (nitida) is from the Latin nitidus meaning "shining", referring to the leaves of this species.

[3] Smithton peppermint is widespread in northern, western and southern Tasmania and also occurs on some Bass Strait Islands.

It grows in forest from sea level to hills and plateaus, sometimes as a mallee in coastal sand dunes.
