Cyperus ustulatus, also known as giant umbrella-sedge{{BSBI 2007 |access-date=2014-10-17 }} or coastal cutty grass is a species of sedge native to New Zealand. C. ustulatus generally grows in coastal or lowland areas near water in the North Island and on the Kermadec Islands.

The leaves are wide, shiny and folded. It produces long, dark brown seed heads after flowering in summer. The seed heads are held by a cluster of leaves at the top of the plant.{{cite web|title=Toetoe upoko-tangata|url=http://www.gw.govt.nz/toetoe-upoko-tangata/|publisher=Greater Wellington Regional Council|access-date=2012-04-15}}

The Māori name for the plant is toetoe upoko-tangata. The word toetoe by itself generally refers to Austroderia which are in Poaceae, a different family.
