Nasserism (Arabic: التَّيَّار النَّاصِرِيّ, romanized: at-Tayyār an-Nāṣiriyy) 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." According to Willard Range's interpretation of Nasserism, Nasserism was assumed "to give the Arab spirit a new lease on life" that would one day "make Arabs self-confident". Showing that this ideology was not created for political reform, rather as liberation towards outside perspectives.
Many other Arab countries have adopted Nasserist forms of government during the 20th century, most being formed during the 1960s, including Algeria under the FLN and the Libyan Arab Republic under Muammar Gaddafi. The Nasserist ideology is also similar in theory to the Ba'athist ideology which was also notably practiced under Saddam Hussein's Ba'athist Iraq (1968–2003) and under the Assad family's Ba'athist Syria (1963–2024).
