Squawfish or pikeminnows are cyprinid fish of the genus "Ptychocheilus" consisting of four species native to western North America. Voracious predators, they are considered an "undesirable" species in many waters. This is largely due to the species' perceived tendency to prey upon small trout and salmon. "Squawfish" is their traditional name. In 1999, the American Fisheries Society adopted "pikeminnow" as the name it recommends, because some Native Americans considered "squawfish" offensive.

The Colorado pikeminnow, "P. lucius", is the largest member of the genus, averaging 4 to 9 pounds (2 to 4 kg) in adult fish with occasional specimens up to 25 pounds (11 kg). There are historical and anecdotal reports of Colorado pikeminnows nearing 6 feet (1.8 m) in length and 80 pounds (36 kg) in weight. The species is near extinction in its native Colorado River basin habitat, due to extensive habitat destruction. It too is considered an undesirable species, despite being critically endangered. Critics of the recovery program have suggested that the efforts are hugely expensive and largely unsuccessful.
