Lima is a genus of file shells or file clams, marine bivalve molluscs in the family Limidae, the file shells, within the subclass Pteriomorphia.

The shells are obliquely trigonal, and strongly radially ribbed, the ribs scabrous to spinose.

The soft parts are bright red and many tentacles protrude from the open valves.
