Eucalyptus flocktoniae, commonly known as merrit,[2] is a species of tree or mallee that is endemic to Western Australia.

It has smooth, silvery grey bark, lance-shaped to curved adult leaves, prominently beaked flower buds in groups of seven or nine and barrel-shaped or urn-shaped fruit.

[2][3][4] Merrit was first formally described in 1911 by Joseph Maiden who gave it the name Eucalyptus oleosa var.

[7] The specific epithet (flocktoniae) honours "Miss Margaret Flockton, the accomplished artist of my 'Critical Revision of the genus Eucalyptus' and 'Forest Flora of New South Wales'".

[8] In 1999, Dean Nicolle and John Conran described two subspecies and the names have been accepted by the Australian Plant Census: Eucalyptus flocktoniae usually grows in open woodland and forest on sandy plains.
