Leo Igwe (born 26 July 1970) is a Nigerian human rights advocate and humanist. Igwe is a former Western and Southern African representative of the International Humanist and Ethical Union, and has specialized in campaigning against and documenting the impacts of child witchcraft accusations. He holds a Ph.D from the Bayreuth International School of African Studies at the University of Bayreuth in Germany, having earned a graduate degree in philosophy from the University of Calabar in Nigeria. Igwe's human rights advocacy has brought him into conflict with high-profile witchcraft believers, such as Liberty Foundation Gospel Ministries, because of his criticism of what he describes as their role in the violence and child abandonment that sometimes result from accusations of witchcraft.
