Sushi (すし, 寿司, 鮨, 鮓, pronounced [sɯɕiꜜ] or [sɯꜜɕi] ) is a Japanese dish of prepared vinegared rice (鮨飯, sushi-meshi), usually with some sugar and salt, plus a variety of ingredients (ねた, neta), such as vegetables, and any meat, but most commonly seafood (often raw but can be cooked). Styles of sushi and its presentation vary widely, but the one key ingredient is "sushi rice", also referred to as shari (しゃり), or sumeshi (酢飯).

The creator of modern sushi is believed to be Hanaya Yohei, who invented nigiri-zushi, a type of sushi most known today, in which seafood is placed on hand-pressed vinegared rice, around 1824 in the Edo period (1603–1867). It was the fast food of the chōnin class in the Edo period.

Sushi is traditionally made with medium-grain white rice, though it can be prepared with brown rice or short-grain rice. It is very often prepared with seafood, such as squid, eel, yellowtail, salmon, tuna or imitation crab meat. Many types of sushi are vegetarian. It is often served with pickled ginger (gari), wasabi, and soy sauce. Daikon radish or pickled daikon (takuan) are popular garnishes for the dish.

Sushi is sometimes confused with sashimi, a dish that consists of thinly sliced raw fish or occasionally meat, without sushi rice.
