Abstract: Nowadays, the region of Middle East and North Africa has become a "testing ground" where the competition between the great powers takes place . The importance of this region is determined by its geopolitical position, concentration of large natural resources, as well as the fact that it represents the greatest threat to the international security - the bases of terrorist organizations, the strengthening role of the group "Islamic State", drug trafficking and the proliferation of weapons of mass destruction (WMD). Socialist People's Libyan Arab Jamahiriya was one of the most developed and richest countries on the African continent: the crisis events of 2011, which resulted in the overthrow of the government, the murder of Muammar Gaddafi and the crisis in the country. From the viewpoint of the neoclassical realism the Libyan crisis is explored in the article. The causes of the crisis (both internal and external) as as well as the interests of the great powers - the United States of America, France and Britain are analyzed.
