Corbicula fluminea is a species of freshwater clam, an aquatic bivalve mollusk in the family Cyrenidae. This species is often confused with Corbicula fluminalis due to the two species' similar colour and texture.

The species is of originally mainly Asian origin and thus it is often commonly called Asian clam or Asiatic clam. In the aquarium and koi pond trade, it is often called golden clam or golden freshwater clam. In Southeast Asia, it is known as the prosperity clam or good luck clam.
