Cenchrus echinatus is a species of grass known by the common names southern sandspur, southern sandbur, and in Australia, Mossman River grass.[1][2] It is native to North and South America.

It is a clump-forming annual grass growing up to 80 cm tall. The leaves occur with or without hairs and measure up to 12 mm wide. The ligule is a fringe of hairs. The grass has barbed burrs up 4–10 mm long.

In Australia it forms an invasive weed in coastal situations.[2]
