Buccinum is a genus of medium-sized sea snails, marine gastropod molluscs in the family Buccinidae, the true whelks.

It is provided with a branchial siphon, projecting, thick, very long and dorsal, issuing from the emargination at the base of the shell.

This trunk is armed at its extremity with beaks, which enable the animal to pierce the shell of other molluscs and crustaceans, upon which it preys.

The males are provided with a very large love dart, i.e. an exciting appendage, which, in a state of repose, is situated under the right edge of the mantle.

They are sometimes driven and transported by the waves to distances far removed from the places where they had been deposited; whence the same species of Buccinum are often found in very different climates.

Some species serve for food to the inhabitants of many countries, particularly upon the shores of the English Channel and the North Sea.
