Moxostoma, the redhorses or jumprocks, is a genus of North American ray-finned fish in the family Catostomidae.

Redhorses are variable in size, geographic location, and other ecological traits such as spawning substrate.

[2][3][4] Several redhorses are long-lived (lifespans greater than 20 years), much like many other catostomid species.

[2] Redhorses are broadly of conservation concern, as these long-lived species are highly intolerant to environmental pollution,[5] habitat fragmentation,[5] and are currently subject to unregulated 21st century sport bowfishing which is removing and wantonly wasting several of these species by the ton.

[2] The following 22 species are recognized in this genus:[6] Additionally, four undescribed species are thought to belong to this genus:
