Human Rights Watch mourns the passing of the Colombian human rights defender Gustavo Gallón on June 30, 2026. Gallón, a lawyer and university professor who most recently served as Colombia’s ambassador to the United Nations in Geneva, leaves a remarkable legacy spanning more than five decades in defense of human rights. As founder and longtime director of the human rights group Colombian Commission of Jurists, Gallón advocated tirelessly for accountability, victims’ rights, and the rule of law.
He was a leading advocate in advancing justice and ending impunity for gross human rights violations in Colombia and beyond before national, regional, and international institutions, including Colombia's Special Jurisdiction for Peace and at the International Criminal Court.
His work ranged from remote regions of Colombia to Haiti, Equatorial Guinea, and the United Nations. Before serving as Colombian ambassador, he served as special representative of the UN Commission on Human Rights for Equatorial Guinea from 1999 to 2002 and as the independent expert on Haiti for the UN Human Rights Council from 2013 to 2017, always in pursuit of dignity and justice, always in service to and solidarity with victims and survivors.
As Colombian ambassador to the Human Rights Council, he was known for his integrity, his passion, and his centering of victims, survivors, and affected communities. That was true both in welcoming scrutiny of and attention to Colombia’s own human rights challenges, or supporting justice and standing in solidarity with victims of abuses around the world.
These included Palestine, as well as issues related to the environment and climate, women’s rights, and the situation of human rights defenders. He was a strong supporter of civil society and proponent of their role in inter-governmental processes and had a reputation as a reflective, kind, and principled leader in the human rights community in Geneva.
“Gustavo will be very fondly remembered for his integrity, intellectual rigor, and unwavering commitment to human rights,” said Juanita Goebertus, Americas director at Human Rights Watch. “He will be greatly missed, but his contributions leave an indelible mark on Colombia and the global human rights movement. We extend our heartfelt condolences to his family, friends, and the many colleagues and partners who had the privilege of working alongside him over decades of principled advocacy.”
