Arroz de marisco is a delicious Portuguese dish consisting of rice and various seafood ingredients. Unlike the popular Spanish paella, this Portuguese variety is not completely reduced and is often described as a thick rice stew. It can employ various seafood ingredients such as prawns, mussels, squid, or clams, and is usually seasoned with fresh herbs and white wine, then complemented with vegetables such as peas or tomatoes.

With the possible origin in Leira, the dish is traditionally associated with coastal areas, and it is one of the most popular seafood dishes in the country.
