Peace camps are a form of physical protest camp that is focused on anti-war and anti-nuclear activity. They are set up outside military bases by members of the peace movement who oppose either the existence of the military bases themselves, the armaments held there, or the politics of those who control the bases. They began in the 1920s and became prominent in 1982 due to the worldwide publicity generated by the Greenham Common Women's Peace Camp. They were particularly a phenomenon of the United Kingdom in the 1980s where they were associated with sentiment against American imperialism but Peace Camps have existed at other times and places since the 1920s.

A peace movement is a social movement which seeks to achieve ideals such as the ending of a particular war or minimizing inter-human violence in a particular place or situation. They are often linked to the goal of achieving world peace. Some of the methods used to achieve these goals include advocacy of pacifism, nonviolent resistance, diplomacy, boycotts, peace camps, ethical consumerism, supporting anti-war political candidates, supporting legislation to remove profits from government contracts to the military–industrial complex, banning guns, creating tools for open government and transparency, direct democracy, supporting whistleblowers who expose war crimes or conspiracies to create wars, demonstrations, and political lobbying. The political cooperative is an example of an organization which seeks to merge all peace-movement and green organizations; they may have diverse goals, but have the common ideal of peace and humane sustainability. A concern of some peace activists is the challenge of attaining peace when those against peace often use violence as their means of communication and empowerment.
