Triplofusus giganteus, commonly known as the Florida horse conch, or the giant horse conch, is a species of extremely large predatory subtropical and tropical sea snail, a marine gastropod mollusc in the family Fasciolariidae, the spindle snails, tulip snails and their allies. On average, it weighs over 11 pounds (5.0 kg).

Although known as a horse conch, this is not a true conch, as it is not in the family Strombidae.

With a shell length that can reach 60 centimetres (24 in), this species is the largest gastropod in United States waters, and one of the largest gastropods in the world.
