The common periwinkle, Littorina littorea, is a species of sea snail, a marine gastropod mollusc of the family Littorinidae. It was given its Latin name by Linnaeus in 1758. The common periwinkle is mainly found on rocky coasts and muddy habitats on the northeastern and northwestern shores of the Atlantic Ocean. The species can also tolerate brackish water. Periwinkles sometimes live in small tide pools ranging from 1 to 2 m or about 3 to 6 feet in size.

Edible or common periwinkles have long been gathered from the shore for food. Like its land relation, the garden snail, the periwinkle moves on a muscular, fleshy foot lubricated by a film of mucus. When not active, it often nestles in a crack or gully and during low tide when it is exposed to the air, it can seal the gap between its shell and the rock with mucus to prevent desiccation. The shell of the periwinkle is spiral shaped, and so is its visceral mass.

Periwinkles feed by grazing along the surface on which they live. They use their radula to scrape algae from rocks, or to pick up algae from the film that covers the surface of mud in estuaries or bays.

World-wide there are numerous species of periwinkle, all of which live in the intertidal zone. Some species live very high up in the splash zone, a part of the shore that is dry almost all of the time, and these species are virtually land snails.

Periwinkles are a delicacy in African and Asian cuisine. The meat is high in protein but low in fat content; it is estimated to have 15% protein, 2.4% fat and about 80% water. Periwinkles are also eaten in Britain and Ireland where they are commonly simply referred to as "winkles."

In English-speaking countries in other parts of the world, gastropod molluscs from other families, such as the Nerites, Neritidae, are sometimes commonly known as "winkles", simply because they are small marine snails that occupy a similar ecological niche.

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
