Law enforcement in Belarus is the responsibility of a variety of agencies such as the Militsiya, as well as other agencies such as the Presidential Guard and the State Security Agency of the Republic of Belarus, all under the authority of the country's Ministry of Internal Affairs.

The Ministry of Internal Affairs has cooperated with several international law enforcement organisations including Interpol and the United Nations Office on Drugs and Crime. Examples also include the Organization for Security and Co-operation in Europe which, under the auspices of many projects and programmes, has helped develop Belarusian law enforcement capabilities.
