Rasboroides pallidus is a species of freshwater cyprinid fish endemic to southwestern Sri Lanka. It is only known from shallow, slow-flowing streams in the basins of the Kalu River, Bentara River, Gin River, Polathu-Modera River and Nilwala River. It has been introduced to the Mahaweli and Walawe River basins, and is overall less threatened than the related R. vaterifloris.
