Malleidae, or the hammer oysters, is a family of saltwater clams. They are related to the pearl oysters, in the order Pterioida.[1]

The shells of most of them are T-shaped, with the hinge at the top of the T, and with the byssus emrging from the hinge. An oblique ligament holds the hinge. The shell is partially nacreous. There is a single, large adductor muscle. The exhalant current exits at the hinge.

Most hammer oysters live in tropical, coralline areas.
