Peace News (PN) is a pacifist magazine first published on 6 June 1936 to serve the peace movement in the United Kingdom. From later in 1936 to April 1961 it was the official paper of the Peace Pledge Union (PPU), and from 1990 to 2004 was co-published with War Resisters' International.

The Peace Pledge Union (PPU) is a non-governmental organisation that promotes pacifism, based in the United Kingdom. Its members are signatories to the following pledge: "War is a crime against humanity. I renounce war, and am therefore determined not to support any kind of war. I am also determined to work for the removal of all causes of war", and campaign to promote peaceful and nonviolent solutions to conflict. The PPU forms the British section of War Resisters' International.
