Alcohol Beverage Services, previously known as the Department of Liquor Control is a government agency within the County of Montgomery, Maryland, and is the wholesaler of beer, wine and spirits alcoholic beverage throughout the county's 507-square-mile (1,310 km2) area.

Montgomery County's Liquor Control Board was created under the terms of Section 159 of Article 2B of the Annotated Code of Maryland.

[citation needed] A Maryland law passed in 1978 prohibited chain and discount stores from having alcohol licenses.

[9][10] The chain-store law was enacted in the early 1980s after a push from small, local retail businesses.

[10] The 7-Eleven license was challenged in 2017 by small business retailers and eventually revoked in 2018 for violating the chain-store restriction.
