Cyathochaeta is a genus of rhizomatous perennial sedges.

The leaves are mostly basal, often with one cauline and have ligule membranes.

When flowering they produce a panicle-like, narrow inflorescence with distant nodes containing several spikelets at each node with a single bisexual flower.

[2] There are six known species all of which are endemic to Australia.

[2] The genera was first described in 1848 by the German botanist Christian Gottfried Daniel Nees von Esenbeck.
