Acacia amyctica is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

It has smooth, light-grey coloured bark and slightly ribbed, sparsely hairy branchlets.

[2][3][4][5] Acacia amyctica was first formally described in 1995 by Richard Sumner Cowan and Bruce Maslin in the journal Nuytsia from specimens collected near Salmon Gums in 1983.

[4] This species of Acacia grows in flat, low woodland or in open mallee shrubland, its distribution limited to mostly between Salmon Gums and Grass Patch, but also in Peak Charles National Park and around Dunn Swamp.

[3][4] Acacia amystica is listed as "Priority Two" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions[5] meaning it may be threatened but is poorly known, only occurring in a few locations.
