The International Pfeffer Peace Award or Pfeffer Peace Award is one of the three peace awards presented by the United States Fellowship of Reconciliation (United States) (FOR), along with the Martin Luther King Jr. Award and the Nyack Area Peace Award. Since 1989, it has been awarded annually to "individuals or organizations whose commitment to peace, justice, and reconciliation is recognized as extraordinary." The International Pfeffer Peace Award was established at the end of the 1980s by Leo and Freda Pfeffer to acknowledge and honour leaders and activists who work globally for peace and justice.
