Amblychilepas is a genus of sea snails, marine gastropod mollusks in the family Fissurellidae, the keyhole limpets.

Amblychilepas is closely associated with Dendrofissurella and Medusafissurella with which it shares radular and shell characters.

The upper mantle fold only slightly envelops the edge of the shell.

Contrary to Dendrofissurella and Medusafissurella, the foremost part of the foot (propodium) is unmodified.

The large outer lateral tooth of the radula is quadricuspid ( = with four cusps).
