Porteresia coarctata is a species of grass in the Poaceae family, native to India, Sri Lanka, Bangladesh, and Myanmar.

Porteresia coarctata is considered by some botanists to be the only species in the genus Porteresia. Other authors maintain instead that it should belong in the rice genus Oryza, as Oryza coarctata Roxb. It is a form of wild rice that grows in saline estuaries in Bangladesh 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.
