Clam digging is a North American term for a common way to harvest clams from below the surface of the tidal sand flats or mud flats where they live. It is done both recreationally and commercially. Commercial digging in the U.S. and Canada is colloquially referred to as clamming, and is done by a clammer.

Soft-shell clams or Sand gaper, scientific name Mya arenaria, popularly called "steamers", "softshells", "piss clams", "Ipswich clams", or "Essex clams", are a species of edible saltwater clam, a marine bivalve mollusk in the family Myidae.
