Misgurnus is a genus of true loaches found in Europe and Asia. The origin of the name Misgurnus comes from the Greek word miseo (to hate) and the Turkish gür (loud), a name given to them due to their habit of becoming very active during barometric pressure changes that occur during thunderstorms. The common names, weather loach or weatherfish, also derive from this behavior. Some species of misgurnus are eaten, mostly in Asia, and are also sold as pets in the aquarium trade. Their average size can range from 6 to over 12 inches.

There are currently 12 recognized species in this genus:^[2]
