The Vistula barbel (Barbus waleckii) is a disputed species of European freshwater fish in the cyprinid genus Barbus.

More recently, it has been hypothesized to be a natural hybrid that originated from a common barbel (B. barbus) female mating with a Carpathian barbel (B. carpathicus) male.

Nevertheless, the populations do not seem to represent first-generation hybrids.

It is recorded or suspected from Poland, Slovakia and Ukraine.
