A dry county is a county in the United States whose government forbids the sale of any kind of alcoholic beverages. Some prohibit off-premises sale, some prohibit on-premises sale, and some prohibit both. Hundreds of dry counties exist across the United States, a majority of them in the South. A number of smaller jurisdictions also exist, such as cities, towns, and townships, which prohibit the sale of alcoholic beverages. These are known as dry cities, dry towns, or dry townships.
Although the 21st Amendment repeals nationwide prohibition in the United States, it allows for prohibition under state or local laws. Prior to and after repeal of nationwide prohibition, some states passed local option laws granting counties and municipalities, either by popular vote or ordinance, the ability to decide for themselves whether to allow alcoholic beverages within their jurisdiction. Many dry communities do not prohibit the consumption of alcohol, which could potentially cause a loss of profits and taxes from the sale of alcohol to their residents in wet (non-prohibition) areas.
The rationale for maintaining prohibition at the local level is often religious in nature, as many evangelical Protestant Christian denominations discourage the consumption of alcohol by their followers (see Christianity and alcohol, sumptuary law, and Bootleggers and Baptists). While state law does not allow for dry counties, laws designed to restrict the sale and consumption of alcohol are common in the mostly LDS (Mormon) state of Utah. Consumption of alcohol is discouraged by the LDS Church.
