Tomato juice is a juice made from tomatoes, usually used as a beverage, either plain or in cocktails such as a Bloody Mary or Michelada.

In Canada, tomato juice is unconcentrated and pasteurized, made from fine tomato pulp from ripe and whole tomatoes. The stems and skins must be removed without adding water to the final juice product. It may also contain a sweetening agent, citric acid and salt.
