'''''Triodia basedowii''''', commonly known as '''lobed spinifex''', is a species of tussock-forming grass-like plant found in Australia.

It occurs on sandy plains and small hills and dunes of bare red sand. Green to purple flowers are displayed from long scapes at any time of the year, emerging from the short and dense foliage growing no more than 1.3&nbsp;meters high.<ref name="FloraBase">{{FloraBase|id=680}}</ref>

The associated landscape which it dominates is sometimes favoured as habitat of a pebble mound building mouse species ''Pseudomys chapmani''.<ref name="AustMamm1983">{{cite encyclopedia | last = Kitchener | first = D.J. | author-link = D.J.
