Roméo Antonius Dallaire is a retired Canadian politician and military officer who was a senator from Quebec from 2005 to 2014, and a lieutenant-general in the Canadian Armed Forces. He notably was the force commander of UNAMIR, the ill-fated United Nations peacekeeping force for Rwanda between 1993 and 1994, and for trying to stop the genocide that was being waged by Hutu extremists against Tutsis. Dallaire is a Senior Fellow at the Montreal Institute for Genocide and Human Rights Studies (MIGS) and co-director of the MIGS Will to Intervene Project.

The United Nations Assistance Mission for Rwanda (UNAMIR) was established by United Nations Security Council Resolution 872 on 5 October 1993. It was intended to assist in the implementation of the Arusha Accords, signed on 4 August 1993, which was meant to end the Rwandan Civil War. The mission lasted from October 1993 to March 1996. Its activities were meant to aid the peace process between the Hutu-dominated Rwandese government and the Tutsi-dominated rebel Rwandan Patriotic Front (RPF). The UNAMIR has received much attention for its role in failing, due to the limitations of its rules of engagement, to prevent the Rwandan genocide and outbreak of fighting. Its mandate extended past the RPF overthrow of the government and into the Great Lakes refugee crisis. The mission is thus regarded as a major failure.
