Humanists International

Humanists International (known as the International Humanist and Ethical Union, or IHEU, from 1952–2019) is an international non-governmental organisation championing secularism and human rights, motivated by secular humanist values. Founded in Amsterdam in 1952, it is an umbrella organisation made up of more than 160 secular humanist, atheist, agnostic, rationalist, skeptic, freethought and Ethical Culture organisations from over 80 countries, as of 2025.
Humanists International campaigns globally on human rights issues, with a specific emphasis on defending freedom of thought and expression and the rights of the non-religious, who are often a vulnerable minority in many parts of the world. The organisation is based in London but maintains a presence at the United Nations Human Rights Council in Geneva, the United Nations General Assembly in New York, and the Council of Europe in Strasbourg, among other international institutions.
