The minimum legal drinking age refers to that age at which consuming an alcoholic beverage is permitted by law. This may differ from the minimum age at which one can purchase alcohol -- Indonesia, for example, focuses only on a minimum legal purchasing age.

Some consider the legal drinking age an arbitrary age restriction that promotes alcohol abuse in much the same way as prohibition did in the United States.
