The anti-nuclear movement in the Philippines aimed to stop the construction of nuclear power facilities and terminate the presence of American military bases, which were believed to house nuclear weapons on Philippine soil. Anti-nuclear demonstrations were led by groups such as the Nuclear-Free Philippines Coalition (NFPC) and No Nukes Philippines. Coalitions argued that American bases in the Philippines perpetuated nuclear threats from other opponent nations of the United States, and that nuclear testing was transpiring in these bases. The nuclear threats and the bases also represented foreign intervention from the United States, which was a staunch issue among nationalists.

The anti-nuclear movement is a social movement that opposes various nuclear technologies. Some direct action groups, environmental movements, and professional organisations have identified themselves with the movement at the local, national, or international level. Major anti-nuclear groups include Campaign for Nuclear Disarmament, Friends of the Earth, Greenpeace, International Physicians for the Prevention of Nuclear War, Peace Action, Seneca Women's Encampment for a Future of Peace and Justice and the Nuclear Information and Resource Service. The initial objective of the movement was nuclear disarmament, though since the late 1960s opposition has included the use of nuclear power. Many anti-nuclear groups oppose both nuclear power and nuclear weapons. The formation of green parties in the 1970s and 1980s was often a direct result of anti-nuclear politics.
