Police Scotland (Scottish Gaelic: Poileas Alba), officially the Police Service of Scotland (Seirbheis Phoilis na h-Alba), is the territorial police force responsible for law enforcement and crime prevention in Scotland. It was formed in 2013, through the merging of eight regional police forces in Scotland, as well as the specialist services of the Scottish Police Services Authority, including the Scottish Crime and Drug Enforcement Agency. Although not formally absorbing it, the merger also resulted in the winding down of the Association of Chief Police Officers in Scotland.
Police Scotland is the second-largest territorial police force in the United Kingdom (after the Metropolitan Police) in terms of officer numbers, and the largest territorial force in terms of its geographic area of responsibility. The chief constable is answerable to the Scottish Police Authority, and the force is inspected by His Majesty's Inspectorate of Constabulary in Scotland.
