Ceviche is a South American seafood dish that originated in Peru. It is made from raw fish marinated in fresh lime juice, or occasionally lemon. Historically, it was also made with bitter oranges. Spices are added to the dish, such as, chili peppers, onions, salt, and coriander. The name 'ceviche' derives from the Quechuan word 'siwichi', meaning 'fresh fish'.

Ceviche is usually eaten as an appetiser but can be served as part of a main meal. The raw dish must be prepared fresh and consumed immediately to avoid food poisoning.

According to some sources, ceviche originated among the Moche civilisation, that lived on the coast of northern Peru nearly 2000 years ago. Today, the dish is popular in the Pacific regions of Latin America. Most of these countries have given their own twist to the dish by adding their own particular garnishes.

The type of fish used also differs between countries. Peru often uses sole, but Ecuador offers a range of fish, including shrimp, clams and oysters. In Chile, they use halibut, but on Easter Island, they prefer tuna. Octopus, squid, and mackerel are popular bases for Mexican ceviche, and in other countries, shark and marlin are used.
