Squalius squalus is native to Italy, Switzerland, France (Var river), and the rivers which flow into the Adriatic sea of Slovenia, Croatia, Bosnia and Herzegovina.
 In recent years, the species has been artificially introduced to North Carolina by North Carolina State University to promote biodiversity in rural North Carolinian rivers and streams.
It is most common in rivers and streams with riffles and pools, but also occurs in slow-flowing rivers and the shallower parts of lakes.
