Nasserism is an Arab nationalist and Arab socialist political ideology based on the thinking of Gamal Abdel Nasser, one of the two principal leaders of the Egyptian Revolution of 1952, and Egypt's second President. Spanning the domestic and international spheres, it combines elements of Arab socialism, republicanism, secularism, nationalism, anti-imperialism, developing world solidarity, Pan-Arabism, and international non-alignment. According to Mohamed Hassanein Heikal, Nasserism symbolised "the direction of liberation, socialist transformation, the people’s control of their own resources, and the democracy of the peoples working forces."

Arab nationalism is a political ideology asserting that Arabs constitute a single nation. As a traditional nationalist ideology, it promotes Arab culture and civilization, celebrates Arab history, glorifies the Arabic language as well as Arabic literature, and calls for the rejuvenation of Arab society through total unification. It bases itself on the premise that the people of the Arab world — from the Atlantic Ocean to the Arabian Sea — constitute one nation bound together by a common identity: ethnicity, language, culture, history, geography, and politics.
