Acacia tetragonophylla, commonly known as curara, kurara or dead finish, is a tree in the family Fabaceae that is endemic to arid and semi-arid parts of central and western Australia.

[2] The glabrous phyllodes are formed in groups of two to six on dwarf, knotty and lateral branchlets or singly on new shoots.

The phyllodes have a slender linear shape ending in a sharp point and are mostly pentagonal to compressed in cross-section with five to seven prominent nerves.

In Western Australia it is found in the Pilbara, Gascoyne, Mid West, Wheatbelt and Goldfields-Esperance regions.

[3] The species was first formally described by the botanist Ferdinand von Mueller in 1863 as part of the work Fragmenta Phytographiae Australiae.
