Oryza coarctata, synonym Porteresia coarctata, is a species of grass in the family Poaceae, native to Pakistan, India, Bangladesh, and Myanmar. It is a perennial species that shows substantial underground rhizomatous growth. The rhizome tissues give out aerial shoots in a favourable season.

Oryza coarctata is a form of wild rice that grows in saline estuaries and is harvested and eaten as a delicacy. The plant is salt-tolerant, and is seen as a possibly important source of salt-tolerance genes for transfer to other rice species. It is closely related to Oryza australiensis. The leaves of this species secrete salt through special microhair like structures that have three morphotypes, and a method to isolate these structures has been developed.
