Cyperus papyrus (papyrus sedge, paper reed, Indian matting plant, Nile grass) is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water.

Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians—it is the source of papyrus paper, one of the first types of paper ever made. Parts of the plant can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant.

In nature, it grows in full sun, in flooded swamps, and on lake margins throughout Africa, Madagascar, and the Mediterranean countries.

C. papyrus and the dwarf cultivar C. papyrus 'Nanus' have gained the Royal Horticultural Society's Award of Garden Merit.

This tall, robust, leafless aquatic plant can grow 4 to 5 m (13 to 16 ft) high. It forms a grass-like clump of triangular green stems that rise up from thick, woody rhizomes. Each stem is topped by a dense cluster of thin, bright green, thread-like stems around 10 to 30 cm (4 to 10 in) in length, resembling a feather duster when the plant is young. Greenish-brown flower clusters eventually appear at the ends of the rays, giving way to brown, nut-like fruits.

The younger parts of the rhizome are covered by red-brown, papery, triangular scales, which also cover the base of the culms. Botanically, these represent reduced leaves, so strictly it is not quite correct to call this plant fully "leafless".

Egyptians used the plant (which they called aaru) for many purposes, most famously for making papyrus. Its name in Greek and in English is widely believed to have come from Egyptian. Cyperus papyrus is now used mainly for decoration, as it is nearly extinct in its native habitat in the Nile Delta, where in ancient times it was widely cultivated. Theophrastus' History of Plants (Book iv. 10) states that it grew in Syria, and according to Pliny's Natural History, it was also a native plant of the Niger River and the Euphrates.
