The Microcerberidae are a family of isopod crustaceans.

They are less than 2 mm (0.079 in) long, and live interstitially in shallow marine or freshwater sand habitats.

[2] Marine microcerberids comprise the main part species diversity, but are very alike.

As a group, they have very broad distribution: Freshwater taxa are less abundant in species number (only 12 species), but are more morphologically diverse and include seven or eight genera.
