Eucalyptus urna, commonly known as merrit,[2] is a species of mallet or marlock that is endemic to southern areas of Western Australia.

Eucalyptus urna is a mallet or marlock that typically grows to a height of 16 m (52 ft) but does not form a lignotuber.

[2][3][4] Eucalyptus urna was first formally described in 1999 by Dean Nicolle in Australian Systematic Botany from specimens collected by Ian Brooker near Newdegate in 1988.

[5] The specific epithet (urna) is a Latin word meaning water jar or urn, referring to the shape of the fruit.

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