Corydoras nanus is a tropical freshwater fish belonging to the Corydoradinae sub-family of the Callichthyidae family. It originates in inland waters in South America, and is found in the Suriname and Maroni River basins in Suriname and the Iracoubo River basin in French Guiana. It was originally described by H. Nijssen and I. J. H. Isbrücker in 1967.

This fish has been found in creeks with a moderate current, 0.5 to 3 m wide, shallow (20 cm to 50 cm depth) with sandy to sandy-muddy bottom and not brightly illuminated. It will grow in length up to 1.7 inches (4.5 centimeters). It lives in a tropical climate in water with a 6.0 - 8.0 pH, a water hardness of 2 - 25 dGH, and a temperature range of 72 - 79 °F (22 - 26 °C). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs. In captivity, eggs have been deposited mostly on plant leaves. The female may produce up to 600 eggs.

Corydoras nanus is of commercial importance in the aquarium trade industry.
