A liquor store is a retail business that predominantly sells prepackaged alcoholic beverages, including liquors, wine or beer, usually intended to be consumed off the store's premises. Depending on region and local idiom, they may also be called an off-licence, off-sale, bottle shop, bottle store or, colloquially, bottle-o, liquor store or other similar terms. A very limited number of jurisdictions have an alcohol monopoly. In US states that are alcoholic beverage control (ABC) states, the term ABC store may be used.

Liquor is an alcoholic drink produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation. Other terms for liquor include: spirit, distilled beverage, booze, spirituous liquor or hard liquor. The distillation process concentrates the liquid to increase its alcohol by volume. As liquors contain significantly more alcohol (ethanol) than other alcoholic drinks, they are considered "harder." In North America, the term hard liquor is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term spirits is more commonly used in the UK. Some examples of liquors include vodka, rum, gin, and tequila. Liquors are often aged in barrels, such as for the production of brandy and whiskey, or are infused with flavorings to form flavored liquors, such as absinthe.
