Sannantha similis is a species in the myrtle family, Myrtaceae and is endemic to eastern Australia.

It is a shrub with narrowly lance-shaped leaves, and groups of three white flowers arranged in leaf axils.

[2][3][4] This species was first formally described in 1997 by Anthony Bean who gave it the name Babingtonia similis in the journal Austrobaileya from specimens collected near Springbrook in 1994.

[5] In 2007, Peter Gordon Wilson transferred the species to Sannantha as S. similis in Australian Systematic Botany.

[3] Sannantha similis grows in a range of habitats, including open forest and rainforest margins, from near Brisbane in south-eastern Queensland to near Newcastle in New South Wales.
