Melaleuca systena, commonly known as coastal honeymyrtle is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia.

It is a small shrub with crowded foliage and profuse heads of white to yellow flowers on the ends of its branches in spring.

[2] Melaleuca systena was first named in 1999 by Lyndley Craven and Brendan Lepschi in Australian Systematic Botany.

[7] The specific epithet (systena) is from the Ancient Greek word systenos meaning "tapering"[8] referring to the shape of the leaf.

[2] This melaleuca occurs on the coast in and between the Shark Bay and Augusta districts[2] in the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain, Warren and Yalgoo biogeographic regions.
