光头稗（学名：Echinochloa colona）为禾本科稗属下的一个种。

Echinochloa colona is a type of wild grass originating from tropical Asia. It was formerly classified as a species of Panicum. It is the wild ancestor of the cultivated cereal crop Echinochloa frumentacea, sawa millet. Some taxonomists treat the two taxa as one species, in which case the domesticated forms may also be referred to as E. colona.
