Eleocharis montevidensis is a species of spikesedge known by the common name sand spikerush. It is a widespread coastal plant native to the Americas. It grows in moist, sandy spots in many habitat types, including lakes, riverbanks, wet meadows, and springs.

The narrow grasslike leaves are dark purplish or reddish brown at the bases, becoming lighter in color toward the tips, and drying to a thin, papery texture. The inflorescence is an oval-shaped spikelet appearing at the tip of the stem. It is under a centimeter long and made up of several flowers covered in brownish bracts.[3]
