The International Physicians for the Prevention of Nuclear War (IPPNW) is a global federation of medical professionals dedicated to advocating for a world free from the threat of nuclear weapons. Founded in 1980, this organisation harnesses the moral authority and expertise of physicians to highlight the catastrophic humanitarian and environmental consequences of nuclear warfare.

Through research, education, and advocacy, IPPNW seeks to influence policy and public opinion, promoting disarmament and fostering peace. Their efforts have been recognised globally, earning them the Nobel Peace Prize in 1985. With a commitment to safeguarding human health and the environment, IPPNW continues to be a pivotal voice in the global peace movement.
