Agnès Paulette Solange Callamard (French pronunciation: [aɲɛs kalamaʁ]; born 14 March 1963) is a French human rights activist who is the Secretary General of Amnesty International. She was previously the Special Rapporteur on extrajudicial, summary, or arbitrary executions appointed by the United Nations Human Rights Council, and the former Director of the Columbia University Global Freedom of Expression project.

A native of Pierrelatte, France, Callamard received her undergraduate degree from the Institut d'Études Politiques de Grenoble in 1985. She earned a master's degree in international and African studies from Howard University in 1988. Callamard received a PhD in Political Science from the New School for Social Research in New York City, with a thesis titled "Populations Under Fire, Population Under Stress: A Study of Mozambican Refugees and Malawian villagers in Malawi" in 1995.

Callamard has conducted human-rights investigations in a number of countries in Africa, Asia, and the Middle East. She has published in the field of human rights, women's rights, refugee movements and accountability. Callamard has worked extensively in the field of international refugee movements, including work with the Center for Refugee Studies in Toronto.

In May 2017, Callamard attended a conference in the Philippines, which was followed by her Wikipedia page being vandalized. Callamard stated that the visit was not in an official capacity.

From 1998 to 2001, Callamard was Chef de Cabinet for the Secretary General of Amnesty International and the organisation's Research Policy Coordinator.

In January 2013, Callamard tweeted that Shimon Peres had admitted in a New York Times interview that Yasser Arafat was murdered. In April 2021, Amnesty International released a statement that the tweet was not reflective of the position of Amnesty International or Callamard. Jewish News wrote "[t]he tweet was still available on Callamard's account".

In 2001, Callamard was the founding director of the Humanitarian Accountability Partnership International, where she oversaw field trials in Afghanistan, Cambodia and Sierra Leone and created an international self-regulatory body for humanitarian agencies committed to strengthening accountability to disaster-affected populations. She was in this position until 2004.

In October 2004, Callamard took the position of Executive Director of Article 19, an international human-rights organization.
