Baeckea omissa is a species of flowering plant in the family Myrtaceae and is endemic to eastern Australia.

It is a shrub with egg-shaped to lance-shaped leaves with the narrower end towards the base and white flowers mostly with ten to fifteen stamens.

[2][3] Baeckea omissa was first formally described in 1997 by Anthony Bean in the journal Telopea from specimens he collected near Tenterfield in 1993.

[2][4] The specific epithet (omissa) means "neglected or overlooked", referring to the late recognition of this taxon.

[2] This baeckea grows in heathy swamp and is common and widespread from near Stanthorpe in Queensland to the New England National Park and near Torrington in New South Wales.
