Schistura quasimodo is a species of stone loach (a ray-finned fish) in the genus Schistura. It is known from a single stream from the Nam Ngum drainage in Laos, a tributary of the Mekong. It has a cylindrical body, sometimes with a conspicuous hump (the species epithet refers to Quasimodo, character in Victor Hugo's The Hunchback of Notre-Dame). The known material suggests a maximum standard length of about 48mm.
S. quasimodo has a very restricted distribution and may be threatened by pollution from mining activities, sedimentation from deforestation, and hydro-power development.
