The '''Cyperaceae''' are a [[family (biology)|family]] of [[monocotyledon]]ous [[graminoid]] [[flowering plant]]s known as '''sedges''', which superficially resemble [[Poaceae|grasses]] and [[Juncaceae|rushes]].

Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions) and leaves that are spirally arranged in three ranks (grasses have alternate leaves forming two ranks).<ref name="backyardnature">{{cite web | url=http://www.backyardnature.net/fl_caryx.htm|title=Grasslike non-grasses|publisher=Backyard Nature|accessdate=December 30, 2014}}</ref><ref>{{cite book|author1=Peter W.

Some well-known sedges include the water chestnut (''[[Eleocharis dulcis]]'') and the [[papyrus]] sedge (''[[Cyperus papyrus]]''), from which the [[Ancient Egypt]]ian [[writing material]] was made. This family also includes cotton-grass (''[[Eriophorum]]''), spike-rush (''[[Eleocharis]]''), sawgrass (''[[Cladium]]''), nutsedge or nutgrass (''[[Cyperus rotundus]]'', a common lawn weed), and white star sedge (''[[Rhynchospora colorata]]'').
