Bossiaea cucullata is a species of flowering plant in the family Fabaceae and is endemic to Western Australia.

It is a dense, many-branched shrub with narrow-winged cladodes, leaves reduced to dark brown scales, and yellow and deep red or pale greenish-yellow flowers.

[2][3][4] Bossiaea cucullata was first formally described in 1998 by James Henderson Ross in the journal Muelleria from specimens collected on the western side of Lake King in 1997.

[3][6] This bossiaea grows in deep sand around the edge of salt lakes in the Avon Wheatbelt, Coolgardie, Mallee and Murchison biogeographic regions of Western Australia.

[2][4] Bossiaea cucullata is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
