List of anti-war organizations

In order to facilitate organized, determined, and principled opposition to war, peace-centered activists have often founded anti-war organizations. These groups range from temporary coalitions which address one war or pending war, to more permanent structured organizations which work to end the concept of war and the factors which lead to large-scale destructive conflicts. The overwhelming majority do so in a nonviolent manner. The following list of anti-war organizations highlights past and present anti-war groups from across the world.
