The Dag Hammarskjöld Medal is awarded posthumously by the United Nations to military, police, or civilian personnel who lose their lives while serving in UN peacekeeping operations. In 2025, two Indian servicemen were posthumously conferred this medal by the United Nations, recognising their supreme sacrifice during UN peacekeeping duties.
The medal is named after Dag Hammarskjöld, the second Secretary-General of the UN, who died in a plane crash in 1961 while on a peace mission.
India is one of the largest troop-contributing countries to UN peacekeeping missions, and its personnel have frequently been honoured with this award.
