Agamyxis is a genus of thorny catfishes.

There are currently two recognized species in this genus:

This genus is found in tropical South America.

Both species reach about 15 centimetres (6 in) SL. These species both appear very similar; A. albomaculatus might be slimmer, have more spots and a different pattern on its caudal fin.

These catfish are able to make sounds by grinding their pectoral fin bones against their shoulder bones. They can live for 17 years.

Both species in this genus are popular in the aquarium trade.
