Fishes of the family Cyprinidae include carps, barbs, minnows, etc. They are the most diverse and prevalent group of freshwater species distributed in the aquatic bodies of India and nearby countries. In Kerala they predominate in freshwater capture fisheries. Most of the cyprinids are economically important as ornamental and food fishes. Taxonomic studies conducted on cyprinid species of Kerala state are scarce; no detailed systematic studies were done on these fishes of Kasargod district in Kerala, India.  During this study a detailed survey was conducted on various cyprinoid fish species of Kasargod district. Taxonomically important features such as meristic counts and morphometric characters were analyzed and compared with their congeners. Twenty species of cyprinids were collected during the study period. These species belong to thirteen genera (Barilius, Dawkinsia, Devario, Garra, Haludaria, Hypselebarbus, Labeo, Puntius, Rasbora, Sahyadria, Salmostoma, Systomus, and Tor). They showed their preponderance in most of the aquatic bodies of Kasargod district. Three new species (Barilius cyanochlorus, Hypselobarbus nitidus and Puntius ocellus) were discovered, described, and named during this study period.
