Schistura personata is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded in the Nam San, a tributary of the Nam Ngum in the Mekong Basin of Laos where it can be found in moderately fast or fast flowing streams, among riffles, with a stone or gravel bed. Its population has been impacted by dams and by deforestation, agriculture and small scale gold mining. These factors collectively contribute to a decline in its population.
