John Howard Yoder was an American Mennonite theologian and ethicist best known for his defense of Christian pacifism. His most influential book was The Politics of Jesus, which was first published in 1972. Yoder was a Mennonite and wrote from an Anabaptist perspective. He spent the latter part of his career teaching at the University of Notre Dame.

Christian pacifism is the theological and ethical position according to which pacifism and non-violence have both a scriptural and rational basis for Christians, and affirms that any form of violence is incompatible with the Christian faith. Christian pacifists state that Jesus himself was a pacifist who taught and practiced pacifism and that his followers must do likewise. Notable Christian pacifists include Martin Luther King Jr., Leo Tolstoy, Adin Ballou, Dorothy Day, Ammon Hennacy, and brothers Daniel and Philip Berrigan.
