Tropidophoxinellus alburnoides is a species of fish in the family Cyprinidae. It is found in Portugal and Spain. Its natural habitats are rivers and intermittent rivers. It may be threatened by habitat loss.

Tropidophoxinellus alburnoides is a highly peculiar fish in regard to its evolution and reproduction. It has been derived from hybridisation between females of Squalius pyrenaicus and males of another, unknown cyprinid species, and maintains the genomes of both parental species. Tropidophoxinellus alburnoides may have various numbers of these genomes (polyploidy), and may use different reproductive modes to pass them on to the offspring, including asexual reproduction, normal meiosis and hybridogenesis.
