The 2005 Nobel Peace Prize was awarded to International Atomic Energy Agency and Mohamed ElBaradei "for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way".

United Nations Secretary-General Kofi Annan said he was delighted that the 2005 Nobel Peace Prize had been awarded to the UN nuclear watchdog and its head ElBaradei. "The secretary-general congratulates him and the entire staff of the agency, past and present, on their contributions to global peace," a spokesman for Annan said.

In his Nobel speech, ElBaradei said that the changing landscape of nuclear non-proliferation and disarmament may be defined by the emergence of an extensive black market in nuclear material and equipment, the proliferation of nuclear weapons and sensitive nuclear technology, and the stagnation in nuclear disarmament. To combat proliferation, ElBaradei has suggested keeping nuclear and radiological material out of the hands of extremist groups, tightening control over the operations for producing the nuclear material that could be used in weapons, and accelerating disarmanent efforts. Dr. ElBaradei also stated that only 1% of the money spent on developing new weapons would be enough to feed the entire world and that, if we hope to escape self-destruction, then nuclear weapons should have no place in our collective conscience, and no role in our security.

The Nobel Peace Prize (Norwegian and Swedish: Nobels fredspris) is one of the five Nobel Prizes bequeathed by the Swedish industrialist and inventor Alfred Nobel, along with the prizes in Chemistry, Physics, Physiology or Medicine, and Literature. It is awarded to those who have "done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses."

Per Alfred Nobel's will, the recipient is selected by the Norwegian Nobel Committee, a 5-member committee appointed by the Parliament of Norway. Since 1990, the prize is awarded in Oslo City Hall on 10 December each year. The prize was formerly awarded in the Atrium of the University of Oslo Faculty of Law (1947–89), the Norwegian Nobel Institute (1905–46) and the Parliament (1901–04).

According to Nobel's will, the Peace Prize shall be awarded to the person who "shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses."
