"Mactra" is a genus of medium-sized marine bivalve mollusks or clams, commonly known as trough shells or duck clams. "Mactra" is the type genus within the family Mactridae.

The word "trough" in the common name refers to the fact that all "Mactra" shells have a large ligamental pit at the hinge line, which in life contains a large internal ligament. Most bivalves in other families have an external ligament instead.
