Peace church, or the historic peace churches, designates those Christian denominations that have opposed the use of violence, and in particular participation in war, on the grounds that it is opposed to the teachings of Jesus.

The best known of these groups are: Mennonites, Brethren in Christ, Quakers, Amish, and the Hutterites. Many members of these churches are conscientious objectors to military conscription.

The Jehovah's Witnesses are also opposed to military participation, but are not usually grouped with the historic peace churches.
