Humanists International 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, rationalist, agnostic, skeptic, freethought and Ethical Culture organisations from over 80 countries.

Secular humanism is a philosophy, belief system, or life stance that embraces human reason, logic, secular ethics, and philosophical naturalism, while specifically rejecting religious dogma, supernaturalism, and superstition as the basis of morality and decision-making.
